查看VRRP 详细信息
查看VRRP的接口状态
VRRPV3
(1) 配置Router A
1 配置接口IPv6地址。
[RouterA-GigabitEthernet1/0/1] ipv6 address fe80::1 link-local
[RouterA-GigabitEthernet1/0/1] ipv6 address 1::1 64
2创建备份组1,并配置备份组1的虚拟IPv6地址为FE80::10和1::10。
[RouterA-GigabitEthernet1/0/1] vrrp ipv6 vrid 1 virtual-ip fe80::10 link-local
[RouterA-GigabitEthernet1/0/1] vrrp ipv6 vrid 1 virtual-ip 1::10
3 配置Router A在备份组1中的优先级为110,高于Router B的优先级100,以保证Router A成为Master负责转发流量。
[RouterA-GigabitEthernet1/0/1] vrrp ipv6 vrid 1 priority 110
4 配置Router A工作在抢占方式,以保证Router A故障恢复后,能再次抢占成为Master,即只要Router A正常工作,就由Router A负责转发流量。为了避免频繁地进行状态切换,配置抢占延迟时间为5000厘秒。
[RouterA-GigabitEthernet1/0/1] vrrp ipv6 vrid 1 preempt-mode delay 5000
5 配置允许发布RA消息,以便Host A通过RA消息学习到缺省网关地址。
[RouterA-GigabitEthernet1/0/1] undo ipv6 nd ra halt
(2) 配置Router B
1 配置接口IPv6地址。
[RouterB-GigabitEthernet1/0/1] ipv6 address fe80::2 link-local
[RouterB-GigabitEthernet1/0/1] ipv6 address 1::2 64
2创建备份组1,并配置备份组1的虚拟IPv6地址为FE80::10和1::10。
[RouterB-GigabitEthernet1/0/1] vrrp ipv6 vrid 1 virtual-ip fe80::10 link-local
[RouterB-GigabitEthernet1/0/1] vrrp ipv6 vrid 1 virtual-ip 1::10
3 配置Router B工作在抢占方式,抢占延迟时间为5000厘秒。
[RouterB-GigabitEthernet1/0/1] vrrp ipv6 vrid 1 preempt-mode delay 5000
4 配置允许发布RA消息,以便Host A通过RA消息学习到缺省网关地址。
[RouterB-GigabitEthernet1/0/1] undo ipv6 nd ra halt
4. 验证配置
配置完成后,在Host A上可以ping通Host B。通过display vrrp ipv6 verbose命令查看配置后的结果。
