BFD (for BGP) question

,

Hi !

I’ve configured not agressive timers 1000/1000/5 ( like MSK-IX suggests)
But 'sh ip bgp neighbors … ’ shows that timers is 300/300/3 ?

What timers are used for BGP process 300/300/3 or 1000/1000/5 ?

Hi @lexxa77 , the BFD output is correct.
It a bug in FRR with output for bgp neighbor.

“the issue is: the daemons that are using BFD does not have a way to get notified about timer value changes, so they always display whatever was configured or the defaults”
