HI All,
Need some advise... I have a couple of MX5 routers which are currently peering via several devices, i.e not directly connected.
The peering is currently up and stable.. Is it possible to add BFD without restarting the peering?
I have added the following config on both sides;
set protocols bgp group outside-outside-ipv6 neighbor 2a00:xxx:3::xx traceoptions file bgp-bfd
set protocols bgp group outside-outside-ipv6 neighbor 2a00:xxx:3::xx traceoptions flag bfd detail
set protocols bgp group outside-outside-ipv6 neighbor 2a00:xxx:3::xx bfd-liveness-detection minimum-interval 300
set protocols bgp group outside-outside-ipv6 neighbor 2a00:xxx:3::xx bfd-liveness-detection session-mode multihop
Though unfortunatly both sides shows the exact same output of Admindown state;
law@rt1..net# run show bfd session extensive
Detect Transmit
Address State Interface Time Interval Multiplier
2a00:xxx:3::xx Down 0.000 2.000 3
Client BGP, TX interval 0.300, RX interval 0.300

Remote min TX interval 0.000, min RX interval 0.000, multiplier 0
Local discriminator 17, remote discriminator 0
Echo mode disabled/inactive, no-absorb, no-refresh
Multi-hop min-recv-TTL 1, route table 0, local-address 2a00:xxx:3::xx
Session ID: 0x1f60dc
1 sessions, 1 clients
Cumulative transmit rate 0.5 pps, cumulative receive rate 0.0 pps
(p.s... no logs captured from the bfd trace)
Do I have to bounce the session??? Or is it possible to bring up BFD on a BGP session transparently??
Thanks in advance...
