VRRP-E short-path forwarding and revertible option
Under the VRRP-E VRID configuration level, use the short-path-forwarding command. If the
revertible option is not enabled, the default behavior will remain the same. Use the following
command to enable short path forwarding.
The track-port command will monitor the status of the outgoing port on the backup. It will revert
back to standard behavior (no short-path forwarding) temporarily even if short-path forwarding is
configured.
Brocade(config-if-e1000-vrid-2)#short-path-forwarding revert-priority 60
Syntax: [no] short-path-forwarding [revert-priority <value>]
Use the supplied priority value as a threshold to determine if the short-path-forwarding behavior
should be effective or not. If one or more ports tracked by the track-port command go down, the
current priority of VRRP-E will be lowered by a specific amount configured in the track-port
command for each port that goes down.
Once the current-priority is lower than the threshold, short path forwarding will be temporarily
suspended and revert back to the regular VRRP-E forwarding behavior (non-short path forwarding
behavior).
The reverting behavior is only temporary. If one or more of the already down ports tracked by the
track-port command come back, it is possible that the current priority of VRRP-E will be higher than
the threshold again and the short-path-forwarding behavior will be resumed.
