Support to activate BFD strict mode for BGP peer sessions (ACX5448, ACX710, cRPD, MX10003, MX10004, VRR, QFX5110, and QFX5200)—Starting in Junos OS Release 23.2R1, we support the activation of BFD strict mode for BGP peer sessions that disallows BGP to establish a session until BFD session is successfully established and has stabilized. With the BFD strict mode feature, you can prevent routing churn and minimize network interruption.
To activate BFD strict mode for BGP peer sessions, include the
strict-mode [bfd-wait-timeout <10-255 seconds>
CLI statement underbfd-liveness-detection
at the[edit protocols bgp group group-name neighbor address]
hierarchy level.For example, use the following command to activate BFD strict mode for BGP peer sessions:
set protocol bgp group group-name neighbor address bfd-liveness-detection [strict-mode [bfd-wait-timeout 10-255 seconds]]
