MHSRP配置(多组热备份路由协议)

一、拓扑

2、目的

在路由器R1和R2上配置多组热备份路由协议(MHSRP),为网络提供冗余路由和负载均衡。

3、配置

(1)、将WEB路由器配置为一个WEB服务器,并配置路由器的用户名、vty和安全口令、IP地址,启动HTTP管理服务。

config terminal

hostname web

interface fastethernet 0/0

ip address 10.1.1.4 255.255.255.0

no shutdown

exit

line vty 0 4

password gzy

login

enable secret class

exit

ip http server

(2)、配置R1和R2路由器

R1:

config terminal

hostname R1

interface fastethernet 0/0

ip address 10.1.1.2 255.255.255.0

no shutdown

exit

interface fastethernet 0/1

ip address 10.1.2.2 255.255.255.0

no shutdown

exit

line vty 0 4

password gzy

login

enable secret class

exit

R2:

config terminal

hostname R2

interface fastethernet 0/0

ip address 10.1.1.3 255.255.255.0

no shutdown

exit

interface fastethernet 0/1

ip address 10.1.2.3 255.255.255.0

no shutdown

exit

line vty 0 4

password gzy

login

enable secret class

exit

(3)、在路由器上配置EIGRP(增强型内部网关路由选择协议)WEB:

config terminal

router eigrp 10

network 10.0.0.0

R1:

config terminal

router eigrp 10

network 10.0.0.0

R2:

config terminal

router eigrp 10

network 10.0.0.0

(4)、配置HSRP,测试看下HSRP的作用(实现了路由冗余,但是只有一条路由即活动路由在转发数据,另一条备份路由处于空闲状态)

R1:

config terminal

interface fastethernet 0/1

standby ip 10.1.2.1

standby preempt

R2:

config terminal

interface fastethernet 0/1

standby ip 10.1.2.1

standby preempt

(5)、在R1和R2之间配置MHSRP,将R1和R2配置在两个相同的HSRP组中。对组1来说R1是活动路由器,R2是备份路由器;对组2来说R2是活动路由器,R1是备份路由器。使用HSRP组1的虚拟IP地址配置一半主机的默认网关,使用HSRP组2的虚拟IP地址配置另一半主机的默认网关。

首先删除刚才配置的HSRP

R1:

interface fastethernet 0/1

no standby ip 10.1.2.1

R2:

interface fastethernet 0/1

no standby ip 10.1.2.1

然后配置MHSRP

R1:

interface fastethernet 0/1

standby 1 ip 10.1.2.1

standby 1 preempt

standby 1 track fastethernet 0/0

standby 2 ip 10.1.2.254

standby 2 preempt

standby 2 priority 95

standby 2 track fastethernet 0/0

R2:

interface fastethernet 0/1

standby 1 ip 10.1.2.1

standby 1 preempt

standby 1 priority 95

standby 1 track fastethernet 0/0

standby 2 ip 10.1.2.254

standby 2 preempt

standby 2 track fastethernet 0/0

至此,MHSRP配置完毕,实现了R1和R2路由器之间的冗余和负载均衡。
