Hi everybody, hope you are fine. I'm trying to implement BFD between two ASR9001 routers and a Palo Alto PA-5250 Firewall. I've configured BFD on the routers (under OSPF process)and the Firewall but they are not seeing each other, BFD sessions are not coming up. OSPF neighboring is OK, graceful restart works fine and when the cluster mastership changes everything goes smooth. Thing is that for broadcast segments if I ever loose a Cisco Router it will take 40 seconds for the OSPF process on the Firewall to detect this (dead timer 4xHello, There's a Nexus in the middle of the devices so interfaces link will not go down). This recovery time is not acceptable, is too high.
Has anyone tried to implement BFD between this vendors before? How did it go? Can you help me with the config please?
Another important information I think... there's a bundle Ethernet link on each of the ASR 9001 Routers. There's a port aggregation as well on each of the Firewalls (active/passive cluster). Could that interfere?
IOS-XR Version: Cisco IOS XR Software, Version 6.0.2[Default]
Palo Alto version: 8.0.9
Below you can find topology diagrams and config information.
Cheers,
Luis
