一基本配置
接入层
C
[C]vlan 10
[C]vlan 20
[C-GigabitEthernet1/0/1]port link-type access
[C-GigabitEthernet1/0/1]port access vlan 10
[C-GigabitEthernet1/0/1]port link-type access
[C-GigabitEthernet1/0/1]port access vlan 20
[C]int range G1/0/3 to g1/0/4
[C-if-range]port link-type trunk
[C-if-range]port trunk permit vlan all
D
[D]vlan 10
[D]vlan 20
[D-GigabitEthernet1/0/1]port link-type access
[D-GigabitEthernet1/0/1]port access vlan 10
[D-GigabitEthernet1/0/1]port link-type access
[D-GigabitEthernet1/0/1]port access vlan 20
[D]int range G1/0/3 to g1/0/4
[D-if-range]port link-type trunk
[D-if-range]port trunk permit vlan all
A
[A]vlan 10
[A]vlan 20
[A]vlan 200
[A]int range g1/0/6 g1/0/9
[A-if-range]port link-type trunk
[A-if-range]port trunk permit vlan all
B
[B]vlan 10
[B]vlan 20
[B]vlan 100
[B]int range g1/0/6 g1/0/9
[B-if-range]port link-type trunk
[B-if-range]port trunk permit vlan all
聚合部分
A
[A]interface Bridge-Aggregation 1
[A]int r g1/0/8 g1/0/9
[A-if-range]port link-aggregation group 1
B
[B]interface Bridge-Aggregation 1
[B]int r g1/0/8 g1/0/9
[B-if-range]port link-aggregation group 1
VRRP部分
A
[A]int vlan 10
[A-Vlan-interface10]ip address 192.168.10.252 24
[A]int vlan 20
[A-Vlan-interface20]ip address 192.168.20.252 24
[A-Vlan-interface10]vrrp vrid 1 virtual-ip 192.168.10.254
[A-Vlan-interface10]vrrp vrid 1 priority 110
[A-Vlan-interface20]vrrp vrid 2 virtual-ip 192.168.20.254
B
[B]int vlan 10
[B-Vlan-interface10]ip address 192.168.10.254 24
[B]int vlan 20
[B-Vlan-interface20]ip address 192.168.20.254 24
[B-Vlan-interface10]vrrp vrid 1 virtual-ip 192.168.10.254
[B-Vlan-interface20]vrrp vrid 2 virtual-ip 192.168.20.254
[B-Vlan-interface20]vrrp vrid 2 priority 110
上行跟踪配置
[A]int vlan 200
[A-Vlan-interface200]ip address 20.0.0.1
[A]track 1 interface GigabitEthernet 1/0/1 设置跟踪g1/0/1接口，跟踪号为1
[A]int vlan 200 接入次设备主VLAN
[A-Vlan-interface200]vrrp vrid 1 track 1 priority reduced 30 匹配主VRRP，当跟踪号1里的端口不可达时优先级减少30，因为原来的优先级是120，减少30后为90，比备份设备优先级低，备份设备抢占为主。
[B]int vlan 100
[B-Vlan-interface100]ip address 10.0.0.1
[B]track 1 interface GigabitEthernet 1/0/1
[B]int vlan 100
[B-Vlan-interface100]vrrp vrid 2 track 1 priority reduced 30
