BFD interface configuration is not working on IOS 17.12.4A on C85xx

[mtjandra]

hi all,

Trying to configure BFD on a router interface on C8500-12X running IOS 17.12.4a, but it seemed like the command is gone on this IOS version.

router(config)#int ten 0/0/2
router(config-if)#bfd ?
% Unrecognized command

Anyone know anything about it?

thanks

Hello,

You may have to have the correct license to use that feature. Can you show which license you are using? You might need the "network-advantage" one.

In modern IOS XE versions, BFD is often enabledper routing protocol / OSPF-BGP etc...

router ospf 1
bfd all-interfaces ! Enable BFD for all OSPF-enabled interfaces
! OR per-interface:
interface TenGigabitEthernet0/0/2
ip ospf bfd ! Enable BFD for OSPF on this specific interface

Thanks!

Thank you.. irouting configuration was actually there..

but found the issue was DNA-advantage license needed to be activated.
