Our network engineer is opting for a complete HSRP Active/Active environment. User Badges View All . Anything traversing between VRFs must hit the PAN and be processed (ie - VRF Segmentation). Auto-suggest helps you quickly narrow down your search results by suggesting possible matches as you type. Hello, I need to implement two Palo Alto Firewalls as active/active with multiple VSYS exist. My preference is to run OSPF (or choose your dynamic routing protocol) to switches that support sub-interfaces (ie - most Junipers) thus severing any Layer 2 / bridge loop goofiness and shrinking your broadcast/failure domains. Here's a link to the high-availability section of the PAN-OS documentation: - https://www.paloaltonetworks.com/documentation/70/pan-os/pan-os/high-availability/ha-concepts.html#1... From there you can read Palo Alto Networks' recommendations, along with links to design guides and tech notes relating to both methods of high availability. So, we are going to make ethernet1/4 as HA1 and ethernet1/5 as HA2.To do this, we need to go – Network >> Interface >> Ethernet.And, then need to change the interface type for ethernet1/4 and ethernet1/5 as HA port just like below. The device priority decides which firewall will preferably take the active role and which firewall will take over the passive role when both the … No leaking necessary. Next, you should turn your attention to your load balancers. These simple actions take just seconds of your time, but go a long way in showing appreciation for community members and the LIVEcommunity as a whole! When two Palo Alto Networks firewalls are deployed in an active/passive cluster, it is mandatory to configure the device priority. Maybe I'm misunderstanding what you mean by "global route table". Copyright 2007 - 2021 - Palo Alto Networks. Francis Gonzales 12,013 views. NAT in Active/Active HA Mode. Perhaps I'm missing a piece of this equation? But asymmetrical routing is not the only case where  active/active is required. I am currently working on a network redesign project with all Cisco gear. If both firewalls are active then I can leverage ECMP from Core Switches to Core Firewalls. two vpc to Active-Passive PaloAlto problem Dear community . Current Version: 8.1. This option along with preemption can lead to preemptive loop, refer:When does an HA node go into Suspended state due to Preemption loop ? I'm planning to use ARP load-sharing method for all vlans whom gateways exist on Palo Alto, a transit vlan should be used for each VSYS as a default route towards the coreswitch. I am seeing lots of "unknowns" "n/a" "aged-out" in my traffic logs. And if the network design is fully active/active where the traffic load is distributed across both paths, then active/active is also required. po110 work while po111 will not work. So right now im just using static to do this but BGP could help route leak and make it easier and cleaner. )7K1(VPC) Palo2(Passive)(Inside seg) >>> (L2? Firepower 2100 HA differences Active/Active vs Active/Passive; Announcements. Passive monitoring is the traditional monitoring of a system without affecting any change to the system. The active device continuously synchronizes its configuration and session information with the passive device (in A/P mode) or the Active-Secondary (in A/A mode) using two HA interfaces – HA1 and HA2. Unless you have asymmetric routes (where traffic leaves one firewall and the only way back is through a different firewall), then you should use Active/Passive HA. When this is done, the primary load balancer distributes the network traffic to the most suitable server, while the second load balancer operates in listening mode to constantly monitor the performance of the primary load balancer and is ready at any time to step in and take over the load balancing duties should the prim… I am currently working on a network redesign project with all Cisco gear. I see that the PA's do support A/A HA using VRRP, so I do not see a configuration issue. Date Registered ‎03-19-2014 09:40 PM: Date Last Visited ‎08-01-2018 08:43 PM: Total Messages Posted 1 Latest Contributions by JayBlanchard. Or were you running a core pair of switches southbound and terminating SVIs there? I am thinking of running active/active on a pair of 5250's in the network core due to the fact that southbound is a pair of core switches that are running alternating HSRP groups or even GLBP. That's your VRF convergence point. High Availability links of PAN firewall in general . I think focusing on the Core Switch Layer (nexus/cat9k) that has multiple VRFs that egress Layer 3 routed ports on the Core to the Core Palo FW. Then, interVRF matches interZone and intraVRF matches intraZone. 1. It doesn't matter which default route is preferred in your route tables (and yes, ECMP works awesome). Failover Traffic from Palo Alto Active Firewall to Passive Firewall: February 16, 2019 February 16, 2019 Raghavendra Seshumurthy . It also introduces complexity because you have three HA interfaces compared to two. The member who gave the solution and all future visitors to this topic will appreciate it! You must configure the following settings on each firewall in an HA pair in an active/active deployment. Both firwalls will synchronise their network, object, and policy configurations plus session information. Passive vs. (This last part in thanks to my Panorama instructor). That depends on your design and preferences. Views. Click Accept as Solution to acknowledge that the answer to your question has been provided. But asymmetrical routing is not the only case where active/active is required. So your SVIs run on layer 3 interfaces/sub-interfaces on the Palos. If the OSPF/BGP,etc protocol come up before the firewalls are completely synced, you will get some drops. If you are running internet facing routers, you can redistribute from there back into the PAN. Then each VRF will have routes for every other VRF. You can do VRF on the 9Ks all day long. Active Monitoring. https://www.paloaltonetworks.com/documentation/70/pan-os/pan-os/high-availability/ha-concepts.html#1... DOTW: TCP Resets from Client and Server aka TCP-RST-FROM-Client, Having issues with GoDaddy redirect sites from IP 184.168.131.241. Active/active mode has faster failover and can handle peak traffic flows better than active/passive mode because both firewalls are actively processing traffic. Here is a sample of interface output. I've done both. Honestly, you should try really hard to avoid it. The following procedure shows how to configure a pair of firewalls in an active/passive deployment as depicted in the following example topology. With PAN Active/Passive the secondary (passive) node has interfaces connected, link is up but no traffic will pass until the device becomes active. Should my ha session options be different than they are? You can create a 0.0.0.0/0 static route on the PAN and redistribute from there. 6691. jfigueroa8.

Steps: Login to the active device through webui https://PA-FW-IP-Address; Go to Device; Click on high availability; Click on operational commands; Click “Suspend local device” Now secondary firewall will move to Active status. What should my ecmp settings be? According to all deployment documentation, HA Active/Passive seems to be the preferred methed for the Palo Alto's. Were you using them as your core routing point for all your vlans? To fix this, you can manually or script the ports connected to the PANs to turn on only after a full sync has occurred. 12. It's really up to you. L3-p2p? These settings do not sync from one peer to another. i need your help with the following data center firewall design and implementation. To configure an active/passive HA pair, first complete the following workflow on the first firewall and then repeat the steps on the second firewall. Active/Passive vs. Active/Active General Topics. For all other cases, use Active/Passive. HA Ports on Palo Alto Networks Firewalls. This technicalpaper describes the main functionality of PAN-OS high availability . User account menu. Posted by 3 months ago. ECMP in Active/Active HA Mode. Joe from the LIVEcommunity Team picks a... Let’s look back before we move on. ARP Load-Sharing. Active/active mode is recommended if each firewall needs its own routing instances and you require full, real-time redundancy out of both firewalls all the time. With PAN Active/Passive the secondary (passive) node has interfaces connected, link is up but no traffic will pass until the device … The physical HA interfaces locations are designed such a way that it is easily understood at a glance. Joe from the LIVEcommunity Team picks a... Let’s look back before we move on. You can either span the vlan all the way through to the PAN subinterfaces or route between the PAN & the 9Ks. According to all deployment documentation, HA Active/Passive seems to be the preferred methed for the Palo Alto's. In this mode the physical link state of data interfaces of the passive firewall will be down and displayed as red. Auto-suggest helps you quickly narrow down your search results by suggesting possible matches as you type. I have HA session owner to first packet and session setup to first packet as well. Prerequisites for Active/Passive … In addition to the floating IP address, the HA peers also need HA links—a control link (HA1) and a data link (HA2)—to synchronize data and maintain state information. Anyone running Palo Altos in the core active/active? You would most likely be pushing the local VLAN GW with DHCP. If one of the PANs fail, the failover is instantaneous. Active/Passive HA Configuration in Palo Alto Firewall: HA Ports: We do not have any dedicated HA1 and HA2 ports. OSPF is used to advertise loopbacks into the route table and the 9500s and palos are using iBGP for the main routing protocol. Failover. )7K2(VPC) How should this be done in order to maintain redundancy? Public Statistics. The LIVEcommunity thanks you for your participation! Can someone provide the pro's and con's of deploying the PA's in an A/P vs. A/A environment? LACP and LLDP Pre-Negotiation for Active/Passive HA. So OSPF is doing ecmp to loopbacks from 9500s to palos, palos doing ecmp to each 9500. is this design right and how can i connect the two nexus vpc to the firewall. These sub-interfaces are then segmented by VRF/vRouter/(choose your terminology) which are then assigned to security zones on the PAN. Are there any performance implications? Home; VM-Series; VM-Series Deployment Guide ; Set Up the VM-Series Firewall on AWS; High Availability for VM-Series Firewall on AWS; Configure Active/Passive HA on AWS; Download PDF. Log in sign up. Our network engineer is opting for a complete HSRP Active/Active environment. I am seeing multiple-paths from the core 9500s and the palos. and if we disconnect po110, po111 will work. You have to think of them as 2 routers that just happen to shared a session table. Palo Alto Networks offers a line of purpose-built security solutions that integrate firewall and VPN functions with a set of high availability (HA) tools to deliver resilient, high performance devices. Helpful. PAN does strongly prefer active/passive. So I have this setup and it appears to be "working" but I seem to be having some issues with ECMP and sessions. Palo Alto – What Settings Don’t Sync in Active/Active HA? Device Priority and Preemption. the firewall aggregated interface will not work with two different vpc port-channels . Steve Puluka BSEET - IP Architect - DQE Communications (Metro Ethernet/ISP). Close. For example: Let's say you have a single PAN vRouter and all of it's attached interfaces (ie - VRFs on the 9K) all in an OSPF area 0. It has its use case, but it really complicates troubleshooting. But, they must be allowed through by your FW rules in the PAN. 65. The LIVEcommunity thanks you for your participation! Using active passive in this manner does deliver high availability in the traditional definition. These simple actions take just seconds of your time, but go a long way in showing appreciation for community members and the LIVEcommunity as a whole! 6044 ‎11-24-2015 02:37 PM: View All . I have ran them active/active at the core. An Active/Passive configuration will offer you many advantages, so consider buying a pair of load balancers and configuring them in H/A mode. Click Accept as Solution to acknowledge that the answer to your question has been provided. In order for the Palo to come back down to a different VRF the Palo needs to know about thise VRF networks in the global route table. OSPF would take care of it from there. So what are you doing to redistribute routes and default routes into vrfs and global route tables? Palo Alto Networks; Support; Live Community; Knowledge Base; MENU. But if you network design is fully active/active and therefore there is traffic such as bgp, vrrp, or other protocols that need to communicate on secondary links at all times, you must have the PAN cluster setup as active/active. The button appears next to the replies on topics you’ve started. In addition to the failover lag time, this active passive HA cannot span multiple Availability Zones due to the AWS limitation of not allowing ENI moves to span AZs. The core 9500s are running /30 layer 3 links to each palo. There is only one catch in this scenario. My core 9500s (not stacked or using VSS) are dual connected to each Palo Alto in active/active. Connect the HA ports to set up a physical connection between the firewalls. Palo Alto Firewall Part 5 Active Passive HA - Duration: 14:53. Palo Alto Network - Configure Active & Passive HA Configure Active/Passive HA . Yes but then you need to get all your Routing layer subnets per vrf back into the global route table so the palo can route back down to a different vrf. If one firewalls fails for any reason, the other firewall can take over with minimal loss of service. Since the latest release of Palo Alto Network PAN-OS 9.0.0 the VM-Series firewall now supports the VM-Series plugin, a built-in-plugin architecture for integration with public clouds or private cloud hypervisors, with the plugin you can now configure VM-Series firewalls with active/passive high availability (HA) in Azure. Gateways are pushed down by OSPF. This type of setup is known as Active/Active Layer3 High Availability with Multi-chassis link aggregation topology by Palo Alto Networks Design Guide Revision A. Does that make sense? There are two build-in HA interfaces in PA5050 namely HA1 and HA2. Shutdown mode. Active/Active was designed for networks with asymmetric routing. Set Up Active/Passive HA. ACTIVE VS PASSIVE DEFENSE May 16, 2017 Brian Samuels 1 Credits • The majority of this material I learned from Debbie Rosenberg • Current slides have a few differences from the handouts, so if you want these latest, please print them from our website • paloaltobridge.com– wait a day or 2 for them to be posted 2. This is great for preventing layer 2 loops when the active and passive device are simply an alternate path for the same traffic. The passive link state is shutdown by default. Are there any issues when using the PA's in an A/A configuration for VPN termination, etc...? I would give the PAN a single vRouter. yes we are alto running active active in vwire mode. Nah. Active/active is required is if your infratructure requires communication be permitted between devices connected to the secondary firewall at all times. Session Setup. Connecting Active/Passive Palo Alto Pair(850) To Nexus VPC 7K Pair Hello, Palo1(Active)(Inside seg) >>>(L2? Copyright 2007 - 2021 - Palo Alto Networks, DOTW: TCP Resets from Client and Server aka TCP-RST-FROM-Client, Having issues with GoDaddy redirect sites from IP 184.168.131.241. Configuration Item: What Doesn’t Sync in Active/Active? Now are you saying you have ONE vRouter per vrf and then vrouters can talk to each other? Active/Passive Link State. Session Owner. You can tune Active/Passive to have a few second failure time. If PANa is the session owner but PANb receives the packet, it will forward the packet over to the session owner (HA3/HSCI).
