Vrrp With Multiple Vlans Configuration Example - HP 6125G Configuration Manual

# When interface VLAN-interface 3 on Switch A is not available, the detailed information about
VRRP group 1 on Switch B is displayed.

The output shows that when VLAN-interface 3 on Switch A is not available, the priority of Switch
A is reduced to 80 and Switch A becomes the backup. Switch B becomes the master and packets
sent from Host A to Host B are forwarded by Switch B.

VRRP with multiple VLANs configuration example

Network requirements
Switch A and Switch B belong to both VRRP group 1 and VRRP group 2. The virtual IPv6 addresses
•
of VRRP group 1 are 1::10/64 and FE80::10, and those of VRRP group 2 are 2::10/64 and
FE90::10.
• Hosts in VLAN 2 learn 1::10/64 as their default gateway and hosts in VLAN 3 learn 2::10/64 as
their default gateway through RA messages sent by the switches.
In VRRP group 1, Switch A has a higher priority than Switch B. In VRRP group 2, Switch B has a
•
higher priority than Switch A. In this case, hosts in VLAN 2 and VLAN 3 can communicate with
external networks through Switch A and Switch B, respectively, and when Switch A or Switch B fails,
the hosts can use the other switch to communicate with external networks to avoid communication
interruption.
