IPv4 VRRP configuration examples

This section provides examples of configuring IPv4 VRRP applications on switches.

Single VRRP group configuration example

This section provides an example of configuring a single VRRP group on switches.

Network requirements

Switch A and Switch B form a VRRP group and use the virtual IP address 10.1.1.111/24 to provide gateway

service for the subnet where Host A resides, as shown in Figure 16.

witch A operates as the master to forward packets from Host A to Host B. When Switch A fails, Switch

B takes over to forward packets for Host A.

Configuration procedure

1. Configure Switch A:

# Configure VLAN 2.

<SwitchA> system-view

[SwitchA] vlan 2

[SwitchA-vlan2] port ten-gigabitethernet 1/0/5

[SwitchA-vlan2] quit

[SwitchA] interface vlan-interface 2

[SwitchA-Vlan-interface2] ip address 10.1.1.1 255.255.255.0

# Create VRRP group 1 on VLAN-interface 2, and set its virtual IP address to 10.1.1.111.

[SwitchA-Vlan-interface2] vrrp vrid 1 virtual-ip 10.1.1.111

# Assign Switch A a higher priority than Switch B in VRRP group 1, so Switch A can become the

master.

[SwitchA-Vlan-interface2] vrrp vrid 1 priority 110

# Configure Switch A to operate in preemptive mode, so it can become the master whenever it

operates correctly, and set the preemption delay to 5 seconds to avoid frequent status switchover.

[SwitchA-Vlan-interface2] vrrp vrid 1 preempt-mode delay 5
