Issue: https://github.com/FRRouting/frr/issues/17337
PR: https://github.com/FRRouting/frr/pull/17344
What were you trying to do that didn't work?
When doing a BGP Peering with BFD between two FRR peers (peer A and peer B), the BGP is established but the peering takes place twice.
What is the impact of this issue to you?
There is feature (Graceful Restart) that will be buggy if that change is not merged.
Please provide the package NVR for which the bug is seen:
Observed in upstream FRR
How reproducible is this bug?:
Always
Steps to reproduce
You need a a peering, with the following
frr defaults traditional hostname frr-k8s-control-plane log file /etc/frr/frr.log log timestamp precision 3 no ipv6 forwarding service integrated-vtysh-config ! debug bgp keepalives debug bgp neighbor-events debug bgp nht debug bgp updates in debug bgp updates out debug bgp zebra debug bgp bfd debug bfd distributed debug bfd peer debug bfd zebra debug bfd network ! router bgp 64512 no bgp ebgp-requires-policy no bgp hard-administrative-reset no bgp default ipv4-unicast no bgp graceful-restart notification no bgp network import-check neighbor 172.18.0.3 remote-as 4200000000 neighbor 172.18.0.3 bfd ! address-family ipv4 unicast network 5.5.5.5/32 neighbor 172.18.0.3 activate exit-address-family ! address-family ipv6 unicast neighbor 172.18.0.3 activate exit-address-family exit # Peer B router bgp 4200000000 bgp router-id 172.18.0.3 no bgp ebgp-requires-policy no bgp default ipv4-unicast no bgp network import-check neighbor 172.18.0.2 remote-as 64512 neighbor 172.18.0.2 bfd neighbor 172.18.0.2 passive ! address-family ipv4 unicast neighbor 172.18.0.2 activate neighbor 172.18.0.2 next-hop-self exit-address-family exit ! route-map RMAP permit 10 set ipv6 next-hop prefer-global exit ! end
Expected results
# show neigh Connections established 1; dropped 0 <---
Actual results
Connections established 2; dropped 1 Last reset 00:00:39, Notification sent (Cease/BFD Down) External BGP neighbor may be up to 1 hops away.
