BFD Dropping During Firewall Failover

L1 Bithead

Having an issue with BFD. I have BFD configured between the Palo Alto and a couple of routers (BFD Single Hop). When a firewall failover occurs, this causes the BFD peering to drop and come back. I would not anticipate this to happen. This causes a unicast path between multihop BFD peers to drop in turn causing multihop BGP peerings to drop as well.

I saw that document as well, and I agree. I was hoping to find something from Palo about what is synced and what is not, but I haven't been able to find anything. 

Here is a document about what is synced and what not in active/active and active/passive clusters:

Nice find...however, this is contradictive to the above thread...My firewalls are active/passive. This shows that in active/passive pairs the only thing that isn't synced are ICMP sessions. Doesn't say host sessions aren't synced in A/P pair.

Yes I see, probably a little outdated ...

However, your post helped me find this.


Which DOES say host information is not synced. Thank you!
