一、实验拓扑
二、实验要求
三、实验思路
IP地址划分
svi1：172.16.1.0/24
svi2：172.16.2.0/24
四、实验步骤
创建vlan，PC划入对应vlan
[sw1]vlan 2
[sw2]vlan 2
[sw3]vlan 2
[sw4]vlan 2
[sw3]int e0/0/2
[sw3-Ethernet0/0/2]port link-type access
[sw3-Ethernet0/0/2]port default vlan 2
[sw4]int e0/0/2
[sw4-Ethernet0/0/2]port link-type access
[sw4-Ethernet0/0/2]port default vlan 2
创建eth-trunk使sw1和sw2连接的两个物理接口合为成一个eth-trunk
[sw1]int Eth-Trunk 0
[sw1-Eth-Trunk0]q
[sw1]int g0/0/2
[sw1-GigabitEthernet0/0/2]eth-trunk 0
[sw1-GigabitEthernet0/0/5]int g0/0/5
[sw1-GigabitEthernet0/0/5]eth-trunk 0
[sw2]int Eth-Trunk 0
[sw2-Eth-Trunk0]q
[sw2]int g0/0/2
[sw2-GigabitEthernet0/0/2]eth-trunk 0
[sw2-GigabitEthernet0/0/5]int g0/0/5
[sw2-GigabitEthernet0/0/5]eth-trunk 0
汇聚层的所有链路把接口定义为trunk
[sw1]port-group group-member GigabitEthernet 0/0/3 to GigabitEthernet 0/0/4 Eth-Trunk 0
[sw1-port-group]port link-type trunk
[sw1-port-group]port trunk allow-pass vlan all
[sw2]port-group group-member GigabitEthernet 0/0/3 to GigabitEthernet 0/0/4 Eth-Trunk 0
[sw2-port-group]port link-type trunk
[sw2-port-group]port trunk allow-pass vlan all
[sw3]port-group group-member Ethernet 0/0/3 Ethernet 0/0/4
[sw3-port-group]port link-type trunk
[sw3-port-group]port trunk allow-pass vlan all
[sw4]port-group group-member Ethernet 0/0/3 Ethernet 0/0/4
[sw4-port-group]port link-type trunk
[sw4-port-group]port trunk allow-pass vlan all
配置生成树，vlan1在1组，vlan2在2组
[sw1]stp mode mstp
[sw1]stp enable
[sw1]stp region-configuration
[sw1-mst-region]region-name 1
[sw1-mst-region]instance 1 vlan 1
[sw1-mst-region]instance 2 vlan 2
[sw1-mst-region]active region-configuration
[sw2]stp mode mstp
[sw2]stp enable
[sw2]stp region-configuration
[sw2-mst-region]region-name 1
[sw2-mst-region]instance 1 vlan 1
[sw2-mst-region]instance 2 vlan 2
[sw2-mst-region]active region-configuration
[sw3]stp mode mstp
[sw3]stp enable
[sw3]stp region-configuration
[sw3-mst-region]region-name 1
[sw3-mst-region]instance 1 vlan 1
[sw3-mst-region]instance 2 vlan 2
[sw3-mst-region]active region-configuration
[sw4]stp mode mstp
[sw4]stp enable
[sw4]stp region-configuration
[sw4-mst-region]region-name 1
[sw4-mst-region]instance 1 vlan 1
[sw4-mst-region]instance 2 vlan 2
[sw4-mst-region]active region-configuration
sw1为根网桥
sw1与sw2互相备份
[sw1]stp instance 1 root primary
[sw1]stp instance 2 root secondary
[sw2]stp instance 1 root secondary
[sw2]stp instance 2 root primary
sw1为组1的主根，组2的备份根
开启svi接口，配置ip地址
[sw1]interface vlan 1
[sw1-Vlanif1]ip ad 172.16.1.1 24
[sw1]interface vlan 2
[sw1-Vlanif2]ip ad 172.16.2.1 24
[sw2]interface vlan 1
[sw2-Vlanif1]ip ad 172.16.1.2 24
[sw2]interface vlan 2
[sw2-Vlanif2]ip ad 172.16.2.2 24
配置VRRP，实施上行链路追踪，采用主备份方式
vlan1做master，vlan2做backup
[sw1]interface vlan 1
[sw1-Vlanif1]vrrp vrid 1 virtual-ip 172.16.1.254
[sw1-Vlanif1]vrrp vrid 1 priority 120
[sw1-Vlanif1]vrrp vrid 1 track interface GigabitEthernet 0/0/1 reduced 30
[sw1]interface vlan 2
[sw1-Vlanif2]vrrp vrid 1 virtual-ip 172.16.2.254
vlan2做master，vlan1做backup
[sw2]interface vlan 2
[sw2-Vlanif2]vrrp vrid 1 virtual-ip 172.16.2.254
[sw2-Vlanif2]vrrp vrid 1 priority 120
[sw2-Vlanif2]vrrp vrid 1 track interface GigabitEthernet 0/0/1 reduced 30
[sw2]interface vlan 1
[sw2-Vlanif1]vrrp vrid 1 virtual-ip 172.16.1.254
启用DHCP
[sw1]dhcp enable
[sw1]ip pool v1
[sw1-ip-pool-v1]network 172.16.1.0 mask 24
[sw1-ip-pool-v1]gateway-list 172.16.1.254
[sw1]ip pool v2
[sw1-ip-pool-v1]network 172.16.2.0 mask 25
[sw1-ip-pool-v1]gateway-list 172.16.2.254
[sw1]int vlan 1
[sw1-Vlanif1]dhcp select global
[sw1-Vlanif1]int vlan 2
[sw1-Vlanif2]dhcp select global
[sw2]dhcp enable
[sw2]ip pool v1
[sw2-ip-pool-v1]network 172.16.1.0 mask 24
[sw2-ip-pool-v1]gateway-list 172.16.1.254
[sw2]ip pool v2
[sw2-ip-pool-v1]network 172.16.2.0 mask 25
[sw2-ip-pool-v1]gateway-list 172.16.2.254
[sw2]int vlan 1
[sw2-Vlanif1]dhcp select global
[sw2-Vlanif1]int vlan 2
[sw2-Vlanif2]dhcp select global
路由部分还存在问题。。。暂未完成
