F3215-HP Load Balancing Module High Availability Configuration Guide-6PW101

VRRP load balancing mode configuration example

Network requirements

• LB A, LB B, and LB C belong to VRRP group 1 with the virtual IPv6 addresses of FE80::10 and 1::10.

• Hosts on network segment 1::/64 learn FE80::10 as their default gateway through RA messages

sent by the routers. Configure the VRRP group to make sure that when a gateway (LB A, LB B, or LB

C) fails, the hosts on the LAN can access external networks through another gateway.

• VRRP group 1 operates in load balancing mode to make good use of network resources.

• Configure a track entry on LB A, LB B, and LB C to monitor their own GigabitEthernet 0/2. When

the interface on LB A, LB B, or LB C fails, the weight of the corresponding router decreases so that

another router with a higher weight can take over.

Configuration procedure

1. Configure LB A:

# Configure VRRP to operate in load balancing mode.

<LBA> system-view

[LBA] vrrp mode load-balance

# Create VRRP group 1 and configure its virtual IPv6 addresses as FE80::10 and 1::10.

[LBA] interface gigabitethernet0/1

[LBA-GigabitEthernet0/1] ipv6 address fe80::1 link-local

[LBA-GigabitEthernet0/1] ipv6 address 1::1 64

[LBA-GigabitEthernet0/1] vrrp ipv6 vrid 1 virtual-ip fe80::10 link-local

[LBA-GigabitEthernet0/1] vrrp ipv6 vrid 1 virtual-ip 1::10
