ISIS GR实验案例

news 2025/7/27 5:40:38

一、实验

拓扑

路由器R1和R2都为双主控设备，主用板和备用板间形成备份关系。路由器间通过IS-IS协议实现网络互连，并提供GR机制。

要求当R1通过GR方式重启IS-IS进程或者进行主备倒换时转发不中断。

1、基础配置

AR1
system
sysname AR1
int g 0/0/0
ip add 10.0.12.1 24AR2
system
sysname AR2
int g 0/0/0
ip add 10.0.12.2 24

2、路由配置

AR1
isis 1
netw 49.0001.0000.0001.00
int g 0/0/0
isis enableAR2
isis 1
netw 49.0001.0000.0002.00
int g 0/0/0
isis enable

查看ISIS邻居状态

3、GR配置

AR1
isis 1
graceful-restart
graceful-restart no-impact-holdtimeAR2
isis 1
graceful-restart
graceful-restart no-impact-holdtime

查看ISIS GR状态信息
