Additional VRRP and VRRP-E parameter configuration

The revert-priority value parameter uses the priority value as the threshold to determine whether
the short-path forwarding (SPF) behavior is effective. Typically, when short-path forwarding is
enabled, the Backup router enforces SPF. For each port that goes down, the current priority of the
VRRP-E router is lowered by the number specified in the track-port command. When the current
priority is lower than the threshold, the SPF behavior is temporarily suspended and reverts back to
the pre-SPF VRRP-E forwarding behavior. The value range is from 1 through 255.

Displaying short-path forwarding combinations

When short-path forwarding ( SPF) is configured, the output of the following show commands
include the SPF information:

•

show run

•

show ip vrrp-e brief

•

show ip vrrp-e vrid vrid

The following example displays information about VRID 1 when only short-path forwarding is
configured.

Brocade# show ip vrrp-e vrid 1

revert-priority are configured.
