Cisco4506双机冗余配置问题
来源:互联网 发布:知到智慧树登陆 编辑:程序博客网 时间:2024/05/18 01:10
最近有兴趣学习下交换机的配置,在进行双机冗余配置时遇到以下问题:
1)同一个VLAN中的主机能和虚拟网关通讯,但主机之间不能ping 通过。
2)各VLAN中的主机能ping 通各VLAN IP和虚拟网关,但主机之间不能互相通讯。
可能是路由的问题但不知道如何解决,请各位前辈指点一二,谢谢!
下面是网络拓扑说明:
(1)两台Cisco 4506作核心交换,4506A是Master,4506B是备份机,之间通过各自的G1/1连接
(2)楼层交换机是两台3500,分别通过F0/1、F0/2和两台4506的F3/1、F3/2建立冗余线路
以下是我对核心交换机、楼层交换机的配置:
