VRRP+PVST，麻烦大家来检查下什么问题 谢谢
R4和R5是3层交换机，R6和R7则是二层。
核心接入层配置了VRRP和PVST。代码如下：
R4：(F1/13，14，15都是TRUNK口)
R4: vlan 10为主vlan 20 为备份
int vlan 10
ip add 192.168.1.254 255.255.255.0
vrrp 10 ip 192.168.1.100 -----------------设置一个虚地址
vrrp 10 priority 254 -----------------优先级值越高越优先
vrrp 10 preempt -----------------抢占
int vlan 20
ip add 192.168.2.254 255.255.255.0
vrrp 20 ip 192.168.2.100 -----------------设置一个虚地址
vrrp 20 priority 100 -----------------优先级值越高越优先
vrrp 20 preempt -----------------抢占
PVST:
spanning-tree vlan 10 root primary
spanning-tree vlan 20 root secondary
R5: vlan 20为主vlan 10 为备份
int vlan 10
ip add 192.168.1.253 255.255.255.0
vrrp 10 ip 192.168.1.100 -----------------设置一个虚地址
vrrp 10 priority 100 -----------------优先级值越高越优先
vrrp 10 preempt -----------------抢占
int vlan 20
ip add 192.168.2.253 255.255.255.0
vrrp 20 ip 192.168.2.100 -----------------设置一个虚地址
vrrp 20 priority 254 -----------------优先级值越高越优先
vrrp 20 preempt
PVST:
spanning-tree vlan 20 root primary
spanning-tree vlan 10 root secondary
R6:(F0/13，14都是TRUNK口)
F1/5 属于vlan 10
R7:(F0/13，14都是TRUNK口)
F1/5 属于vlan 20
C1 :ip 192.168.1.5 24 192.168.1.100
C2 :ip 192.168.2.5 24 192.168.2.100
问题：
C1只能ping通192.168.1.254（重启所有设备后能ping通192.168.1.100 192.168.2.100 192.168.2.254 - -、、、、）
C2不管重启不重启设备。。只能ping通192.168.2.253...........，，，，- -球各位多多指教 我做5遍了。。。
我所有路由器都是3725. R8R9模拟PC. 关掉路由功能,配IP,指网管.
配置就是按照你帖子里面的配的...没别的配置...
配完后,检查Spann tree的根.和vrrp的master.都OK
PIng 也oK... shaoyung 发表于 2013-8-8 22:47 static/image/common/back.gif
哥们 能指教下？？ 无图无真相！ 在所有设备上SHOW SPA VLAN 20看看。 {:6_273:} 你还是给个拓扑图吧，我都看不懂，你的F1/5 连接什么？ 三层交换机上vlan间路由，你的设备是否需要
开启ip routing ？
R4 和R5 是使用F1/15 trunk 连接在一起的？
trunk allow vlan 2
trunk native vlan 1
配置了么？
spanning-tree mode rapid-pvst ?

无图无真相！
不好意思！！！马上上图，当时忘记了
上图了 大家帮帮忙啊。。。。 ccie34 发表于 2013-8-9 06:47 static/image/common/back.gif

开启ip ...
你好 给图了 可能是模拟器的问题！ 你可以试试保存,重启..我在GNS上做了.ping没有问题
