Vrrp Interface Tracking Configuration Example - HP 6125G Configuration Manual

When Switch A fails, you can still successfully ping Host B on Host A. To view the detailed
information about the VRRP group on Switch B, use the display vrrp ipv6 verbose command.
# When Switch A fails, the detailed information about VRRP group 1 on Switch B is displayed.

Network requirements
Switch A and Switch B belong to VRRP group 1 with the virtual IP addresses of 1::10/64 and
•
FE80::10.
• Host A wants to access Host B on the Internet, and learns 1::10/64 as its default gateway through
RA messages sent by the switches.
