三层架构实验

----------------------本文是学习hicp课程的实验，仅供网友参考学习。-----------------------
实验要求，如下图：

实验思路：
先后步骤：channel > vlan > trunk > stp > svi > vrrp > dhcp

代码实现如下：
[sw1]int eth-trunk 0
[sw1-Eth-Trunk0]q
[sw1]int g0/0/1
[sw1-GigabitEthernet0/0/1]eth-trunk 0
[sw1-GigabitEthernet0/0/1]int g0/0/2
[sw1-GigabitEthernet0/0/2]eth-trunk 0
[sw1]vlan 2
[sw1]int eth-trunk 0
[sw1-Eth-Trunk0]port link-type trunk
[sw1-Eth-Trunk0]port trunk allow-pass vlan 2 #vlan1 是默认通过的，此处再添加vlan2通过。
[sw1]int g0/0/3
[sw1-GigabitEthernet0/0/3]port hybrid tagged vlan 2
[sw1]int g0/0/4
[sw1-GigabitEthernet0/0/4]port hybrid tagged vlan 2

[sw1]stp enable
[sw1]stp mode mstp
[sw1]stp region-configuration
[sw1-mst-region]region-name a
[sw1-mst-region]instance 1 vlan 1 #vlan1放进去组1
[sw1-mst-region]instance 2 vlan 2 #vlan2放进去组2
[sw1-mst-region]active region-configuration #激活

#查看生成树
#[sw1]stp region-configuration
#[sw1-mst-region]dis this
[sw1]stp instance 1 root primary #直接指定组1主根
[sw1]stp instance 2 root secondary #直接指定组2的备根

[sw1]int vlan1
[sw1-Vlanif1]ip add 172.16.2.253 24
[sw1-Vlanif1]int vlan2
[sw1-Vlanif2]ip add 172.16.3.253 24
[sw1]int vlan 1
[sw1-Vlanif1]vrrp vrid 1 virtual-ip 172.16.2.250 #在vlanif1里是主
[sw1-Vlanif1]vrrp vrid 1 priority 101
[sw1-Vlanif1]vrrp vrid 1 track int g0/0/5 reduced 10
[sw1-Vlanif1]int vlanif2
[sw1-Vlanif2]vrrp vrid 1 virtual-ip 172.16.3.250 #在vlanif2里是备
[sw1]ip pool vlan1
[sw1-ip-pool-vlan1]gateway-list 172.16.2.250
[sw1-ip-pool-vlan1]
