本文档介绍MSR系列路由器与VRRP虚地址建立IPsec功能的典型配置举例。
本文档不严格与具体软、硬件版本对应,如果使用过程中与产品实际情况有差异,请参考相关产品手册,或以设备实际情况为准。
本文档中的配置均是在实验室环境下进行的配置和验证,配置前设备的所有参数均采用出厂时的缺省配置。如果您已经对设备进行了配置,为了保证配置效果,请确认现有配置和以下举例中的配置不冲突。
本文档假设您已了解IPsec和VRRP特性。
如图1所示,Router A和Router B同属于一个VRRP备份组,Router A作为Master,Router B作为Backup,要求:Router C和VRRP备份组之间建立基于IKE的IPsec隧道。
图1 MSR系列路由器与VRRP虚地址建立IPSec功能的配置组网图
· 为了让Router A成为Master,需要为Router B配置较低的优先级(默认优先级为100);
· 为了与备份组建立IPsec隧道,Router C上IKE指定对端地址为VRRP虚地址;
本举例是在Release 2317版本上进行配置和验证的。

完成以上配置后,正常情况下,Router C与Router A建立IPsec隧道实现加密通信,当Router A断开后,Router C切换到与Router B的隧道继续进行加密通信,从而避免了通信的中断。
# 可以通过以下显示信息,看到正常情况下Router C与备份组的通信经过Router A。
