the routers do not hear each other's vrrp advertisement messages; the advertisement timers are different; vrrp authentication does not match the neighbor settings. please allow for over 60 seconds for the switchover to take place. post the debugs here if possible. thank you! best regards, ...
The priority is set to 100 using the ‘priority’ command. Authentication has been configured and should be same between both the routers. The Virtual IP is assigned with the config line ‘vrrp 1 ip 10.10.10.10’. VRRP Tutorial Diagram If we bring down the interface connecting to Router0...

VRRP(Virtual Router Redundancy Protocol,虚拟路由冗余协议)是一种可以解决这种问题的容错协议,其协议文本在这里。它保证当主机的下一跳路由器出现故障时,由另一台路由器来代替出现故障的路由器进行工作,从而保持网络通信的连续性和可靠性。一组实现了该协议的路由器向局域网内的主句提供具有高可用性(HA)的虚拟路由器...
