神码VRRP配置

神州数码DCRS-5950
VRRP
在三层交换机上配置VRRP：
5950(config)#vlan 100
5950(config)#int vlan 100
5950(config-if-vlan100)#ip address 192.168.100.1 255.255.255.0
5950(config)#router vrrp 1 // 组号两边一致
5950(config-router)#virtual-ip 192.168.100.254 //虚拟网关 两边必须一致
5950(config-router)#priority 200 // 优先级值越大 优先级越高
5950(config-router)#preempt-mode true // 抢占模式
5950(config-router)#interface vlan 100 // 作用的端口
5950(config-router)#enable //启动vrrp



在路由器上配置VRRP:
RA:
interface GigaEthernet0/3.10
ip address 192.168.10.254 255.255.255.0
encapsulation dot1Q 10
vrrp 10 associate 192.168.10.250 255.255.255.0
vrrp 10 priority 150
vrrp 10 preempt
vrrp 10 track interface GigaEthernet0/4 30
RB:
interface GigaEthernet0/3.10
ip address 192.168.10.253 255.255.255.0
encapsulation dot1Q 10
vrrp 10 associate 192.168.10.250 255.255.255.0
vrrp 10 priority 200
vrrp 10 preempt

决定因素：
1.优先级
2.ip address
