1-15When VLAN-interface 3 recovers, switch A will resume its gateway function as the master.Multiple-VRRP Group ConfigurationNetwork requirementsA switch can function as a backup of multiple VRRP groups.Multiple-VRRP group configuration can implement load balancing. For example, Switch A acts as themaster of VRRP group 1 and a backup in VRRP group 2. Similarly, Switch B acts as the master of VRRPgroup 2 and a backup in VRRP group 1. Some hosts in the network take virtual router 1 as the gateway,while others take virtual router 2 as the gateway. In this way, both load balancing and mutual backup areimplemented.Network diagramFigure 1-5 Network diagram for multiple-VRRP group configurationSwitch AHost CHost BSwitch BVlan-int310.100.10.2/24Vlan-int2202.38.160.1/24VLAN-int2202.38.160.2/24202.38.160.3/2410.2.3.1/24Host A202.38.160.4/24InternetVRRP group 1Virtual IP address 202.38.160.111/24VRRP group 2Virtual IP address 202.38.160.112/24Vlan-int310.100.10.3/24Configuration procedurez Configure Switch A.# Configure VLAN 3. system-view[LSW-A] vlan 3[LSW-A-vlan3] port GigabitEthernet1/0/10[LSW-A-vlan3] quit[LSW-A] interface Vlan-interface 3[LSW-A-Vlan-interface3] ip address 10.100.10.2 255.255.255.0[LSW-A-Vlan-interface3] quit# Configure VLAN 2.[LSW-A] vlan 2
