【华为】默认路由配置

1.配置接入层：
LSW1（LSW3同理）:
vlan batch 10 20
in g0/0/1
port link-type ac
port default vlan 10
in g0/0/2
port link-type ac
port default vlan 20
in g0/0/24
port link-type tr
port tr allow-pass vlan 10 20

2.配置汇聚层，设置网关，实现不同vlan之间的通信：
LSW2（LSW4同理）:
vlan batch 10 20 24
in vlan 10
ip ad 192.168.1.254 255.255.255.0
in valn 20 
ip ad 192.168.2.254 255.255.255.0
in g0/0/1
port link-type tr
port tr allow-pass vlan 10 20
int g0/0/24
port link-type access
port default vlan 24
int vlan 24
ip ad 10.1.1.1 255.255.255.0
dis ip interface brief

3.配置DHCP:
LSW2（LSW4同理）:
ip pool for10
network 192.168.10.0 mask 255.255.255.0    
gateway-list 192.168.10.1    
dns-list 223.5.5.5
in vlan 10
dhcp select global

ip pool for20
network 192.168.20.0 mask 255.255.255.0    
gateway-list 192.168.20.1    
dns-list 223.5.5.5
in vlan 20
dhcp select global

另一种配置dhcp方式（不用配置地址池）：
in vlan 10
dhcp select interface
dhcp server dns-list 223.5.5.5
in vlan 20
dhcp select interface
dhcp server dns-list 223.5.5.5

4.配置核心层：

LSW5：
vlan batch 25 26
int g0/0/1
port link-type access
port default vlan 25
int vlan 25
ip ad 10.1.1.2 255.255.255.0

int g0/0/2
port link-type access
port default vlan 26
int vlan 26
ip ad 10.2.1.2 255.255.255.0

5.配置默认路由：
LSW2：
dis ip routing-table 192.168.30.254
ip route-static 192.168.30.0 255.255.255.0 10.1.1.2
ip route-static 192.168.40.0 255.255.255.0 10.1.1.2

LSW5：
ip route-static 192.168.30.0 255.255.255.0 10.2.1.1
ip route-static 192.168.40.0 255.255.255.0 10.2.1.1
ip route-static 192.168.10.0 255.255.255.0 10.1.1.1
ip route-static 192.168.20.0 255.255.255.0 10.1.1.1

LSW4：
ip route-static 192.168.10.0 255.255.255.0 10.2.1.2
ip route-static 192.168.20.0 255.255.255.0 10.2.1.2
