1.5.2 VRRP Interface Tracking Configuration Example

I. Network requirements
Host A needs to access Host B on the Internet, using FE80::10 as its default
gateway.
Switch A and Switch B belong to VRRP group 1 with the virtual IP address of
FE80::10.
If Switch A operates normally, packets sent from Host A to Host B are forwarded
by Switch A; if Switch A is in work, but its Vlan-interface3 which connects to the
Internet is not available, packets sent from Host A to Host B are forwarded by
Switch B.

III. Configuration procedure
1) Configure Switch A
# Configure VLAN 2.
<SysnameA> system-view
[SysnameA] ipv6
[SysnameA] vlan 2
[SysnameA-vlan2] port ethernet 1/5
[SysnameA-vlan2] quit
[SysnameA] interface vlan-interface 2
[SysnameA-Vlan-interface2] ipv6 address fe80::1 link-local
[SysnameA-Vlan-interface2] ipv6 address 1::1 64
# Create a VRRP group 1 and set its virtual IPv6 address to FE80::10.
