VRRP-E short-path forwarding and revertible option
At the VRRP-E VRID configuration level, use the following command to enable short-path forwarding.
device(config-if-e1000-vrid-2)# short-path-forwarding revert-priority 60
Syntax: [no] short-path-forwarding [ revert-priority value]
The revert-priority value in the short-path-forwarding command works in conjunction with the track-
port command to control forwarding behavior.
The track-port command monitors the status of the outgoing port on the backup. Command behavior
can cause short-path forwarding to be disabled temporarily. This happens because as one or more
ports tracked by the track-port command go down, the current priority of the VRRP-E is lowered by a
specific amount configured in the track-port command for each port. Once the current-priority of the
VRRP-E is lower than the threshold value configured as the revert-priority value, short-path
forwarding is temporarily suspended because the VRRP-E reverts back to its default forwarding
behavior.
To counter this behavior, use the revert-priority value in the short-path-forwarding command as a
control threshold. Short-path forwarding resumes as soon as the VRRP-E priority becomes higher
than the revert priority threshold. (The VRRP-E priority increases by the value configured for the
track port command as each of the ports tracked by the command becomes active again.)
Displaying MCT information
This section describes the commands available to display information about MCT configuration and
operation.
Displaying peer and client states
Use the show cluster config command to display the peer device and client states.
