求助，关于GNS模拟VRRP的问题

locliuhai

先上拓扑图


如图，模拟这样一个环节，R2 R3核心交换，SW1 SW2接入层交换机，接入交换机上联口都是trunk口，下联口ACCESS。
配置VRRP负载分担时出现2个问题，求解答。

问题1：R2 R3相互备份，但是要跳这两条命令出来
R3#
*Mar  1 01:15:02.139: %VRRP-6-STATECHANGE: Vl10 Grp 10 state Backup -> Master
R3#
*Mar  1 01:15:03.587: %VRRP-6-STATECHANGE: Vl10 Grp 10 state Master -> Backup
R3#
*Mar  1 01:16:21.647: %VRRP-6-STATECHANGE: Vl10 Grp 10 state Backup -> Master
*Mar  1 01:16:21.867: %VRRP-6-STATECHANGE: Vl10 Grp 10 state Master -> Backup

两个核心交换机都时不时会这样，不知道哪里有问题。

问题2：下面模拟PC的R4和R5，无法ping通自己的虚拟网关地址。


核心配置：

R2的F1/0有没有什么问题啊

R2的F1/0有没有什么问题啊

比如：我看了这个接口的速率和工作模式，都是100M全双工，ping也没问题的

人气这么点……估计没啥人了，又是一个CSDN……

楼主，用那个思科型号的IOS可以做VRRP 啊？

GNS3上3700系列的都可以，不过好像有点问题，ping不通虚拟网关
