interfacetunnelundointerfacetunnelinterfacetunnel命令用来删除指定的Tunnel接口。Tunnel接只具有本地意义，隧道两端可以使用相同或不同的接。相关配置可参考命令disyinterfacetunnel、source、destination和<Sysname>system-view[Sysname]interfacetunnel3

缺省情况下，不使能GRE的keepalive功能。TunnelGREkeepalive报文。如果超时时间内没有收到隧道对端的回应，则本端重新发送keepalive报文。如果超过最TunneldownKeepalive确认报文时，Tunnel接口的状态将转换为up，否则保持down状态。<Sysname>system-view[Sysname]interfacetunnel0mtu(TunnelInterface
