要在 RT1 上配置 offset 值为 3 的路由策略,实现 RT1-S1/0_RT2-S1/1 为主链路,RT1-S1/1_RT2-S1/0 为备份链路,可以按照以下步骤进行配置:
1. 进入 RT1 的配置模式:
```
RT1# configure terminal
```
2. 创建一个路由策略,并配置 offset 值为 3:
```
RT1(config)# ip route offset 3
```
3. 配置主链路的路由:
```
RT1(config-offset-rt)# ip route RT2-S1/1 interface S1/0
```
4. 配置备份链路的路由:
```
RT1(config-offset-rt)# ip route RT2-S1/0 interface S1/1
```
5. 退出配置模式并保存配置:
```
RT1(config-offset-rt)# exit
RT1(config)# end
RT1# copy running-config startup-config
```
这样,RT1 就会根据路由策略的 offset 值来选择主链路和备份链路,实现 RT1-S1/0_RT2-S1/1 为主链路,RT1-S1/1_RT2-S1/0 为备份链路的配置。请根据实际网络环境和设备配置进行适当调整。

在神州数码路由器中,要实现 RT1-S1/0_RT2-S1/1 为主链路,RT1-S1/1_RT2-S1/0 为备份链路,并配置 offset 值为 3 的路由策略,可以按照以下步骤进行配置:
1. 进入 RT1 的配置模式:
```
configure terminal
```
2. 创建一个路由策略,并配置 offset 值为 3:
```
ip offset-list 3 permit
```
3. 配置主链路的路由:
```
ip route-static RT2-S1/1 S1/0 preference 3
```
4. 配置备份链路的路由:
```
ip route-static RT2-S1/0 S1/1 preference 6
```
5. 退出配置模式并保存配置:
```
exit
save
```
这样,RT1 就会根据路由策略的 offset 值来选择最佳路径,实现 RT1-S1/0_RT2-S1/1 为主链路,RT1-S1/1_RT2-S1/0 为备份链路的配置。请根据实际网络环境和设备配置进行适当调整。
.RT1串行链路、RT2串行链路、FW1、AC1之间分别运行RIP和RIPng协议,FW1、RT1、RT2的RIP和RIPng发布loopback2地址路由,AC1 RIP发布loopback2地址路由,AC1 RIPng采用route-map匹配prefix-list重发布loopback2地址路由。RT1配置offset值为3的路由策略,实现RT1-S1/0_RT2-S1/1为主链路,RT1-S1/1_RT2-S1/0为备份链路,ipv4的ACL名称为AclRIP,ipv6的ACL名称为AclRIPng。RT1的S1/0与RT2的S1/1之间采用chap双向认证,用户名为对端设备名称,密码为Key-1122。
