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
eective. 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 specied 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 congured, the output of the following show commands include the SPF information:
• show run
• show ip vrrp-e brief
• show ip vrrp-e vrid
The following example displays information about VRID 1 when only short-path forwarding is congured.
device# show ip vrrp-e vrid 1

The following example displays information about VRID 1 when short-path forwarding and revert priority are
congured.
