BFD Timer expired

[omprakash.palakuru]

Hi,

I'm getting below logs on ASR1001-X and my connectivity is flapping on a WAN interface.

 %BFDFSM-6-BFD_SESS_DOWN: BFD-SYSLOG: BFD session ld:1 handle:1,is going Down Reason: DETECT TIMER EXPIRED

Is this a BUG? if so, any upgrade to overcome?

Thanks!

Hi

It could be, do you have bfd configured under interfaces related to a routing protocol?

Something like that? Probably you need to adjust the timers. 

interface Fa0/2
ip ospf bfd
bfd interval 250 min_rx 250 multiplier 3
end

router ospf 1
bfd all-interfaces

Yes. BFD configured under interfaces.

I recommend first to verify if your IOS has fixed this issue otherwise it could be upgrade.
