华为三层交换机之间配置VLAN间路由

在华为三层交换机上进行VLAN间路由的配置，主要就是创建VLAN，端口划分，三层VLAN接口地址配置，静态路由或是RIP协议配置。

静态路由配置过程：

PCA:ip address:10.1.1.2/24 gw:10.1.1.1/24(VLAN2路由接口IP地址)

PCB:ip address:10.1.2.2/24 gw:10.1.2.1/24(VLAN3路由接口IP地址)

PCC:ip address:10.1.3.2/24 gw:10.1.3.1/24(VLAN2路由接口IP地址)

S3526A和S352B之间的互联网段为10.1.4.0、24

分配S3526A VLAN4路由接口IP地址为10.1.4.1/24,S3526B VLAN4路由接口IP地址为10.1.4.2/24

三层交换机配置

创建VLAN，把PC划到特定VLAN中：

//创建VLAN

[S3526A]vlan 2

//把端口划到VLAN中

[S3526A-VLAN 2]port ethernet0/9 to ethernet0/12

[S3526A-VLAN 2]vlan 3

[S3526A-VLAN 2]port ethernet0/13 to ethernet0/16

[S3526A-VLAN 2]vlan 4

//交换机B的配置：

[S3526B]vlan 2

[S3526B-VLAN 2]port ethernet0/9 to ethernet0/12

[S3526B-VLAN 2]vlan 4

配置各台PC的网关地址和交换机之间的网段地址：

//进入VLAN接口配置模式：

[S3526A]interface Vlan-interface 2

//配置三层VLAN路由接口地址

[S3526A-Vlan-interface2]ip address 10.1.1.1 255.255.255.0

[S3526A-Vlan-interface2] interface Vlan-interface 3

[S3526A-Vlan-interface3]ip address 10.1.2.1 255.255.255.0

[S3526A-Vlan-interface3] interface Vlan-interface 4

[S3526A-Vlan-interface4]ip address 10.1.4.1 255.255.255.0

[S3526B]interface Vlan-interface 2

[S3526B-Vlan-interface2]ip address 10.1.3.1 255.255.255.0

[S3526B-Vlan-interface2] interface Vlan-interface 4

[S3526B-Vlan-interface4]ip address 10.1.4.2 255.255.255.0

在二台三层交换机上配置非直连网段静态路由：

[S3526A]ip route-static 10.1.3.0 255.255.255.0 10.1.4.2

[S3526B]ip route-static 10.1.1.0 255.255.255.0 10.1.4.1

[S3526B]ip route-static 10.1.2.0 255.255.255.0 10.1.4.1

查看路由表，查看网络互通情况：

[S3526B]display ip routing-table

Routing Table: public net

Destination/Mask Proto Pre Cost Nexthop Interface

10.1.1.0/24 STATIC 60 0 10.1.4.1 Vlan-interface4

10.1.2.0/24 STATIC 60 0 10.1.4.1 Vlan-interface4

10.1.3.0/24 DIRECT 0 0 10.1.3.1 Vlan-interface2

10.1.3.1/32 DIREC T 0 0 127.0.0.1 InLoopBack0

10.1.4.0/24 DIRECT 0 0 10.1.4.2 Vlan-interface4

127.0.0.0/8 DIRECT 0 0 127.0.0.1 InLoopBack0

127.0.0.1/32 DIRECT 0 0 127.0.0.1 InLoopBack0

RlP协议在三层交换机上的配置

1.继续上面的，删除前面配置的静态路由。

[S3526A]undo ip route-static 10.1.3.0 255.255.255.0

[S3526B]undo ip route-static 10.1.1.0 255.255.255.0

[S3526B]undo ip route-static 10.1.2.0 255.255.255.0

2.配置RIP协议：

//交换机B上启用RIP协议

[S3526A]rip

[S3526A-rip]network 10.1.1.0

[S3526A-rip]network 10.1.2.0

[S3526A-rip]network 10.1.4.0

//交换机B上启用RIP协议

[S3526B]rip

[S3526B-rip]network 10.1.3.0

[S3526B-rip]network 10.1.4.0

配置完成即可实现网络互通

查看路由表，查看网络互通情况：

[S3526B]display ip routing-table

Routing Table: public net

Destination/Mask Proto Pre Cost Nexthop Interface

10.1.1.0/24 STATIC 60 0 10.1.4.1 Vlan-interface4

10.1.2.0/24 STATIC 60 0 10.1.4.1 Vlan-interface4

10.1.3.0/24 DIRECT 0 0 10.1.3.1 Vlan-interface2

10.1.3.1/32 DIREC T 0 0 127.0.0.1 InLoopBack0

10.1.4.0/24 DIRECT 0 0 10.1.4.2 Vlan-interface4

0.1.4.2/32 DIRECT 0 0 127.0.0.1 InLoopBack0

127.0.0.0/8 DIRECT 0 0 127.0.0.1 InLoopBack0

127.0.0.1/32 DIRECT 0 0 127.0.0.1 InLoopBack0

查看RlP配置信息如下：

[S3526B-rip]display rip
