22.5.;HSRP中ICMP重定向

提问在HSRP中启用ICMP重定向

回答

Router2#configure terminal
Enter configuration commands, one per line.;End with CNTL/Z.
Router2(config)#interface FastEthernet 1/0
Router2(config-if)#no ip redirects
Router2(config-if)#standby redirects disable
Router2(config-if)#exit
Router2(config)#end
Router2#

22.6.;调整HSRP定时器

提问调整备份路由器接管主用路由器所需时长

回答

Router1#configure terminal
Enter configuration commands, one per line.;End with CNTL/Z.
Router1(config)#interface FastEthernet0/1
Router1(config-if)#standby 1 ip 172.22.1.1
Router1(config-if)#standby 1 priority 120
Router1(config-if)#standby 1 preempt
Router1(config-if)#standby 1 timers 1 3
Router1(config-if)#exit
Router1(config)#end
Router1#

注释缺省Hello包时长为3秒，10秒后会接管，如果主用路由器调整时长，整个组内的路由器都要调整为相同的时长。最短可以到达毫秒Router1(config-if)#standby 1 timers msec 100 msec 300

22.7.;在令牌环网络中使用HSRP

提问在令牌环网络中配置HSRP

如果只用IP协议配置同前面例子，如果还有其他协议，特别是使用了source-route bridging就用下面的配置方法

Router1#configure terminal
Enter configuration commands, one per line.;End with CNTL/Z.
Router1(config)#interface Tokenring0
Router1(config-if)#ip address 172.22.1.3
Router1(config-if)#standby ip 172.22.1.1
Router1(config-if)#standby use-bia
Router1(config-if)#standby priority 120
Router1(config-if)#standby preempt
Router1(config-if)#exit
Router1(config)#end
Router1#
Router2#configure terminal
Enter configuration commands, one per line.;End with CNTL/Z.
Router2(config)#interface Tokenring0
Router2(config-if)#ip address 172.22.1.2
Router2(config-if)#standby ip 172.22.1.1
Router2(config-if)#standby use-bia
Router2(config-if)#standby priority 110
Router2(config-if)#standby preempt
Router2(config-if)#exit
Router2(config)#end
Router2#
