华为组网（跨vlan间通信、ospf区域）
SWA的配置如下：创建vlan 10
interface Eth-Trunk1
port link-type trunk
port trunk allow-pass vlan 10
interface GigabitEthernet0/0/1
port link-type access
port default vlan 10
interface GigabitEthernet0/0/2
eth-trunk 1
interface GigabitEthernet0/0/3
interface GigabitEthernet0/0/4
eth-trunk 1
SWB的配置如下：创建vlan 20
interface Eth-Trunk2
port link-type trunk
port trunk allow-pass vlan 20
interface GigabitEthernet0/0/1
port link-type access
port default vlan 20
interface GigabitEthernet0/0/2
interface GigabitEthernet0/0/3
eth-trunk 2
interface GigabitEthernet0/0/4
interface GigabitEthernet0/0/5
eth-trunk 2
SWC(三层交换机）配置：先创建vlan
interface Vlanif10
ip address 192.168.1.1 255.255.255.0
interface Vlanif20
ip address 192.168.2.1 255.255.255.0
interface Vlanif30
ip address 10.0.1.1 255.255.255.252
interface Vlanif50
ip address 192.168.2.2 255.255.255.252
interface MEth0/0/1
interface Eth-Trunk1
port link-type trunk
port trunk allow-pass vlan 10
interface Eth-Trunk2
port link-type trunk
port trunk allow-pass vlan 20
interface GigabitEthernet0/0/1
port link-type trunk
port trunk allow-pass vlan 30
interface GigabitEthernet0/0/2
eth-trunk 1
interface GigabitEthernet0/0/3
eth-trunk 2
interface GigabitEthernet0/0/4
eth-trunk 1
interface GigabitEthernet0/0/5
eth-trunk 2
interface GigabitEthernet0/0/6
port link-type trunk
port trunk allow-pass vlan 50
SWD的配置：先创建vlan
nterface Vlanif30
ip address 172.16.1.1 255.255.255.0
interface Vlanif40
ip address 172.16.2.5 255.255.255.252
interface Vlanif50
ip address 192.168.2.1 255.255.255.252
interface MEth0/0/1
interface GigabitEthernet0/0/1
port link-type access
port default vlan 30
interface GigabitEthernet0/0/2
port link-type trunk
port trunk allow-pass vlan 40
interface GigabitEthernet0/0/3
interface GigabitEthernet0/0/4
interface GigabitEthernet0/0/5
interface GigabitEthernet0/0/6
port link-type trunk
port trunk allow-pass vlan 50
R1的配置：
interface GigabitEthernet0/0/1.1
vlan-type dot1q 30
ip address 10.0.1.2 255.255.255.252
interface GigabitEthernet0/0/2
ip address 10.1.1.2 255.255.255.252
R2的配置：
interface GigabitEthernet0/0/0.1
vlan-type dot1q 40
ip address 172.16.2.6 255.255.255.252
interface GigabitEthernet0/0/1
interface GigabitEthernet0/0/2
ip address 10.1.1.1 255.255.255.252
配置完成后，开始创建ospf区域：
使用looback0作为router id:
例如：R1
ospf 1
area 0.0.0.0
network 10.1.1.0 0.0.0.3
network 1.1.1.1 0.0.0.0
network 10.0.1.0 0.0.0.3
R1, R2, SWC, SWD的配置相似，分别将对应网段划分到对应区域。
可以用display ospf peer brief检查邻居建立情况。
在SWD上可以通过引入直连路由的形式将其网段加入ospf网络中，命令import route direct
还可以设置区域权限：stub和nssa
进入对应区域设置权限，stub拒绝进和出
nssa可以发送不接收
可利用dis ip routing-table查看变化
ping 和tracert命令使用，检测
