Master IP : 202.38.160.2
The output shows that when VLAN-interface 3 on AC 1 is not available, the priority of AC 1 is
reduced to 80 and it becomes the backup. AC 2 becomes the master and packets sent from the
client to the host are forwarded by AC 2.
VRRP with multiple VLANs configuration example
Network requirements
• The hosts in VLAN 2 use 202.38.160.100/25 as their default gateway and the hosts in VLAN 3 use
202.38.160.200/25 as their default gateway.
• AC 1 and AC 2 belong to both VRRP group 1 and VRRP group 2. The virtual IP address of VRRP
group 1 is 202.38.160.100/25, and that of VRRP group 2 is 202.38.160.200/25.
• In VRRP group 1, AC 1 has a higher priority than AC 2. In VRRP group 2, AC 2 has a higher priority
than AC 1. In this case, hosts in VLAN 2 and VLAN 3 can communicate with external networks
through AC 1 and AC 2 respectively, and when AC 1 or AC 2 fails, the hosts can use the other
switch to communicate with external networks to avoid communication interruption.
