short-path-forwarding

Enables short-path forwarding on a Virtual Router Redundancy Protocol (VRRP) router.
Syntax
short-path-forwarding[revert-priority number]
no short-path-forwarding[revert-priority number]
Command Default

Short-path forwarding is disabled.

Parameters
revert-prioritynumber
Allows additional control over short-path forwarding on a backup router. If you configure this option, the revert-priority number acts as a threshold for the current priority of the session, and only if the current priority is higher than the revert-priority will the backup router be able to route frames. The range of revert-priority is 1 to 254.
Modes

VRRP-E router configuration mode

Usage Guidelines

Short-path forwarding means that a backup physical router in a virtual router attempts to bypass the VRRP-E master router and directly forward packets through interfaces on the backup router.

This command can be used for VRRP-E, but not for VRRP. You can perform this configuration on a virtual Ethernet (VE) interface only.

Enter the no short-path-forwarding command to remove this configuration.

Examples

To enable short-path forwarding for a VRRP-E instance: 

device# configure terminal
device(config)# router vrrp-extended
device(config-vrrpe-router)# slow-start 40 
device(config-vrrpe-router)# short-path-forwarding

To enable short-path forwarding for an IPv6 VRRP-E instance: 

device# configure terminal
device(config)# interface ve 10
device(config-vif-10)# ip vrrp-extended vrid 100
device(config-vif-10-vrid-100)# backup
device(config-vif-10-vrid-100)# short-path-forwarding
