Displaying and clearing VRRP-Ev3 statistics

Several show commands can display statistical information about IPv6 VRRP-Ev3 configurations. To reset the IPv6 VRRP-Ev3 statistics, there is a CLI command.

Before you begin

Before displaying statistics, VRRP-Ev3 must be configured and enabled in your network to generate traffic.

About this task

Use one or more of the following commands to display VRRP-Ev3 information. The commands do not have to be entered in this order.

Procedure

Use the exit command to return to privileged EXEC mode, if required.

Enter the show ipv6 vrrp summary command.

device# show ipv6 vrrp summary

Total number of VRRP session(s)   : 2
Master session count  : 1
Backup session count  : 1
Init session count    : 0

This example shows summary output for the two IPv6 VRRP-E sessions that are configured for virtual routers 18 and 19.

Enter the show ipv6 vrrp 19 detail command.
