HSRP热备份路由
如图 做不同vlan的热备份路由
PC1 vlan1 ； PC2 vlan2
SW1：
enable
configure terminal
hostname SW1
no ip domain lookup
vlan 2
vlan 3
exit
interface fastethernet 0/1
switchport mode access
switchport access vlan 2
interface fastethernet 0/2
switchport mode access
switchport access vlan 3
interface fastethernet 0/3
switchport mode trunk
interface fastethernet 0/4
switchport mode trunk
exit
spanning-tree vlan 1 root primary
spanning-tree vlan 2 root primary
spanning-tree vlan 3 root primary #指定冗余线路
以下省略了一些常规操作
SW2：
ip routing
interface vlan 2
ip address 192.168.1.2 255.255.255.0
standby 1 ip 192.168.1.100
standby 1 preempt
standby 1 priority 200 #默认100 越大优先级高 成为vlan 2主路由设备
interface vlan 3
ip address 192.168.2.2 255.255.255.0
standby 2 ip 192.168.2.100
standby 2 preempt
interface fastethernet 0/1
switchport trunk encapsulation dot1q
switchport mode trunk
SW3：
ip routing
interface vlan 2
ip address 192.168.1.3 255.255.255.0
standby 1 ip 192.168.1.100
standby 1 preempt
interface vlan 3
ip address 192.168.2.3 255.255.255.0
standby 2 ip 192.168.2.100
standby 2 preempt
standby 2 priority 200 #默认100 越大优先级高 成为vlan 3主路由设备
interface fastethernet 0/2
switchport trunk encapsulation dot1q
switchport mode trunk
扩展测试
SW2：
interface vlan 10
ip address 192.168.10.1 255.255.255.0
exit
ip route 192.168.100.0 255.255.255.0 192.168.100.2
R1
interface gig0/0
ip address 192.168.10.2 255.255.255.0
exit
interface loopback 0
ip address 192.168.100.1 255.255.255.0
exit
ip route 192.168.0.0 255.255.0.0 192.168.10.1
