VRRP虚拟路由器冗余协议实战 路由器里的虚拟服务器是什么意思

（一）初始化：

R1:

sys

sysname R1

int g0/0/0

ip add 172.16.2.254 24

int g0/0/1

ip add 172.16.3.254 24

q

R2:

sys

sysname R2

int g0/0/0

ip add 172.16.2.100 24

int e1/0/1

ip add 172.16.1.100 24

q

R3:

sys

sysname R3

int g0/0/0

ip add 172.16.3.200 24

int e1/0/1

ip add 172.16.1.200 24

q

（二）部署OSPF网络

R1:

sys

ospf 1

area 0

network 172.16.2.0 0.0.0.255（255.255.255.0）

network 172.16.3.0 0.0.0.255

q

q

R2:

sys

ospf 1

area 0

network 172.16.2.0 0.0.0.255

network 172.16.1.0 0.0.0.255

q

q

R3:

sys

ospf 1

area 0

network 172.16.3.0 0.0.0.255

network 172.16.1.0 0.0.0.255

q

q

R1:

dis ospf peer brief

（三）配置VRRP协议

R2:

int e1/0/1

vrrp vrid 1 virtual-ip 172.16.1.254

vrrp vrid 1 priority 120

q

dis vrrp

R3:

int e1/0/1

vrrp vrid 1 virtual-ip 172.16.1.254

vrrp vrid 1 priority 110

q

dis vrrp

查看VRRP

R2:

dis vrrp

dis vrrp brief

dis vrrp int

（四）验证VRRP主备切换

S1

int e0/0/1

shut

pc上

tracert 命令验证
