interface LoopBack 1
ip address 114.114.114.114 255.255.255.255
2.链路聚合配置
在CORE1和CORE2之间部署链路聚合Eth-Trunk 1。要求使用LACP模式，最大活动端口数为4，根据拓扑图将相应端口加入聚合组，通过display eth-trunk 1查看聚合状。
CORE1/CORE2
interface Eth-Trunk 1
port link-type trunk
port trunk allow-pass vlan all
mode lacp-static
max active-linknumber 4
interface GigabitEthernet 0/0/8
eth-trunk 1
interface GigabitEthernet 0/0/9
eth-trunk 1

CORE2
dhcp enable
ip pool pool_vlan10
network 192.168.10.0 mask 255.255.255.0
gateway-list 192.168.10.254
dns-list 114.114.114.114
lease 3
ip pool pool_vlan20
network 192.168.20.0 mask 255.255.255.0
gateway-list 192.168.20.254
dns-list 114.114.114.114
lease 3
interface Vlanif 10
dhcp select global
interface Vlanif 20
dhcp select global
display ip pool查看地址池配置并截图
4.MSTP+VRRP配置
（1）在CORE1、CORE2、ACC1、ACC2上配置MSTP域配置，域名姓名缩写，实例10绑定VLAN 10 11，实例20绑定VLAN 20 21。指定CORE1为实例10的根桥，CORE2为实例20的根桥。查看STP端口状态并截图。display stp brief
CORE1
stp mode mstp
stp region-configuration
region-name shn
instance 10 vlan 10 11
instance 20 vlan 20 21
active region-configuration
stp instance 10 root primary
stp instance 20 root secondary

CORE2
stp mode mstp
stp region-configuration
region-name shn
instance 10 vlan 10 11
instance 20 vlan 20 21
active region-configuration
stp instance 20 root primary
stp instance 10 root secondary
ACC1/ACC2
stp mode mstp
stp region-configuration
region-name shn
instance 10 vlan 10 11
instance 20 vlan 20 21
active r
查看STP端口状态并截图。display stp brief

（2）在CORE1、CORE2上配置VRRP，虚拟IP为各VLAN网关地址。CORE1为VLAN 10的Master，CORE2为VLAN 20的Master，查看主备关系并截图。）display vrrp brief
CORE1
interface Vlanif 10
vrrp vrid 10 virtual-ip 192.168.10.254
vrrp vrid 10 priority 120
interface Vlanif 20
vrrp vrid 20 virtual-ip 192.168.20.254
vrrp vrid 20 priority 100
CORE2
interface Vlanif 10
vrrp vrid 10 virtual-ip 192.168.10.254
vrrp vrid 10 priority 100
interface Vlanif 20
vrrp vrid 20 virtual-ip 192.168.20.254
vrrp vrid 20 priority 120
2个都写完后查看主备关系并截图display vrrp brief
5.OSPF路由协议配置
（1） 在CORE1、CORE2、AR1之间配置OSPF进程1，area 0，实现企业内网路由互通。
通过AR1向OSPF下发默认路由指向ISP。要求使用network命令精确宣告互联接口地址，Loopback0接口也宣告入OSPF。
（2）查看邻居状态、查看路由表并截图。display ospf peer brief display ip routing-table
CORE1
ospf 1 router-id 1.1.1.1
area 0
network 1.1.1.1 0.0.0.0
network 12.1.1.1 0.0.0.0
network 192.168.10.251 0.0.0.0
network 192.168.20.251 0.0.0.0

network 2.2.2.2 0.0.0.0
network 12.2.2.1 0.0.0.0
network 192.168.10.252 0.0.0.0
