华三的msr3610和思科的2811做GRE VPN,两边无法通讯,GRE的配置很简单就不贴了;
在2811路由上ping 3610的tunnel ip 出错信息如下:
No tunnel in the physical state of up was found for the packet. Dropped the packet.
在3610上ping 2811的tunnel ip 信息如下:
Ping 192.168.168.1 (192.168.168.1): 56 data bytes, press CTRL_C to break

两边查看tunnel信息都是up
2811上的如下
Tunnel0 is up, line protocol is up

应该怎么解决?
