With the simple BFD configuration - (active mode, single hop, without other parameters) ``` ! bfd peer 11.11.11.11 exit ! ``` The interface with 11.11.11.0/24 is a *virtual* interface, which can be deleted. After BFD FSM is created and session is ok, do these things: 1) delete this interface 2) create this interface 3) set same ip address in this interface Now, everything seems completely restored because all configuration is same. But bad thing happens, BFD session hang on "down" status - ``` root# show bfd peer 11.11.11.11 BFD Peer: peer 11.11.11.11 vrf default ID: 638815827 Remote ID: 0 Active mode Status: down Downtime: 3 second(s) Diagnostics: path down <- caused by destroyed interface Remote diagnostics: ok ``` With the interface creating, `bfdd_sessions_enable_interface()` wrongly compares added interface with the created, even key of this `bfd_session` isn't binded with any interface. So this `bfd_session` will hang on "down" status for ever. So skip the compare in this case (no interface in key) to wake up this `bfd_session`. Signed-off-by: anlan_cs <vic.lan@pica8.com> |
