Does using OSPF for redundnacy to 2 different standalone FW's work

[partners-syn]

Is anyone using OSPF to provide hardware/route failover with 2 different PA models?  (3020 and a 3220).  cannot afford HA 3220 now but would like to have failover to old box.  Palo is saying this is not a support design?  I thought OSPF is network 101 basic design?

Hello,

Not sure why they wiould say it doesnt work. I am running OSPF and have several different PAN models. OSPF is a standard and as long as a device supprots it it will run just fine.

What will not work is two different models in an HA configuration. Perhaps that is what they were referring to?

Hope that helps.

Agreed.  As long as you don't have asynchronous routing or are load balancing with another product to keep your flows on the same firewall (ie - F5),  you should be fine.  Based on your description, I'm guessing you don't have full control over your packet flows and would need an Active/Active setup.  This is not supported on non-identical models.  Perhaps you can describe your environment a little more?
