請問有沒有大佬可以解釋關于交換機的主備問題，配置了好久了，想的起來的都用了，可是就是沒有主備的區分
配置如下
sw1
#
vlan batch 10 20 30 40
#
stp instance 1 root primary
stp instance 2 root secondary
#
stp region-configuration
region-name bian
instance 1 vlan 10 20
instance 2 vlan 30 40
#
interface Vlanif1
#
interface Vlanif10
ip address 192.168.10.253 255.255.255.0
vrrp vrid 10 virtual-ip 192.168.10.254

#
interface Vlanif20
ip address 192.168.20.253 255.255.255.0
vrrp vrid 20 virtual-ip 192.168.20.254
vrrp vrid 20 priority 150
#

兩臺交換機的相同VLAN的IP地址應該是不相同的，但是你的是相同的。生成樹協議應該把某些介面阻塞了，那么這條鏈路就不會生效。
uj5u.com熱心網友回復：
不同的交換機配置相同的vlanif ip會造成路由環路嗎？
uj5u.com熱心網友回復：
不是環路呀，思科的交換機默認是開啟生成樹的，有了生成樹就不會環路的。我的意思是VRRP時，兩個物理介面地址和虛擬出來的網關地址在一個網段內，但是不能沖突呀，按你的配置，在SW12,SW13上配置的VLAN10的IP地址是沖突的。

原來如此，我明白了
謝謝??
