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
vlan10
vlan11
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
show interfaces trunk
show vlan brief
省略了一些常规操作
SW2：
ip routing
spanning-tree vlan 1 root primary
spanning-tree vlan 2 root primary #设置优先级成为vlan2的根交换机
spanning-tree vlan 10 root primary
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
show ip interface brief
show vlan brief
show spanning-tree
show standby
SW3：
ip routing
spanning-tree vlan 3 root primary #设置优先级成为vlan3的根交换机
spanning-tree vlan 11 root primary
interface vlan 2 #SVI
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
在 SW2 与 SW3 上配置 HSRP 链路跟踪(必须要做)
SW2：
interface vlan 2
standby 2 track fastethernet 0/2 priority 150 #此为实际命令 模拟器不全
SW3：
interface vlan 3
standby 3 track fastethernet 0/2 priority 150
路由
SW2：
interface vlan 10
ip address 192.168.10.1 255.255.255.0
exit
ip route 192.168.100.0 255.255.255.0 192.168.10.2
SW3:
interface vlan 11
ip address 192.168.20.1 255.255.255.0
exit
ip route 192.168.100.0 255.255.255.0 192.168.20.2
show ip interface brief
show ip route
R1
interface gig0/0
ip address 192.168.10.2 255.255.255.0
interface gig0/1
ip address 192.168.20.2 255.255.255.0
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
ip route 192.168.0.0 255.255.0.0 192.168.20.1
