VRRP-E Extension for short-path forwarding example

Under the VRRP-E VRID configuration level, there is an option to enable short-path forwarding. To
enable short-path forwarding , enter the following commands.

device (config)# router vrrp-extended

device (config)# interface ve 10

device (config-vif-10)# ip-address 10.10.10.25/24

device (config-vif-10)# ip vrrp-extended vrid 10

device (config-vif-10-vrid-10)# backup priority 50

device (config-vif-10-vrid-10)# ip-address 10.10.10.254

device (config-vif-10-vrid-10)# short-path-forwarding

device (config-vif-10-vrid-10)# activate

Syntax: no short-path-forwarding [ revert-priority value ]

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
