VRRP load balancing mode configuration example
Network requirements
 Router A, Router B, and Router 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 (Router A,
Router B, or Router 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 Router A, Router B, and Router C to monitor their own
GigabitEthernet 1/0/2. When the interface on Router A, Router B, or Router C fails, the weight
of the corresponding router decreases so that another router with a higher weight can take over.

Configuration procedure
1. Configure Router A:
# Configure VRRP to operate in load balancing mode.
<RouterA> system-view
[RouterA] vrrp mode load-balance
# Create VRRP group 1 and configure its virtual IPv6 addresses as FE80::10 and 1::10.
[RouterA] interface gigabitethernet 1/0/1
