靜態路由配置過程：
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之間的互聯網段為10.1.4.0、24
分配S3526A VLAN4路由接口IP地址為10.1.4.1/24,S3526B VLAN4路由接口IP地址為10.1.4.2/24
三層交換機配置
創建VLAN，把PC劃到特定VLAN中：
--------------------------------------------------------------------------------
//創建VLAN
[S3526A]vlan 2
//把端口劃到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
//交換機B的配置：
[S3526B]vlan 2
[S3526B-VLAN 2]port ethernet0/9 to ethernet0/12
[S3526B-VLAN 2]vlan 4
--------------------------------------------------------------------------------
配置各臺PC的網關地址和交換機之間的網段地址：
--------------------------------------------------------------------------------
//進入VLAN接口配置模式：
[S3526A]interface Vlan-interface 2
//配置三層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
--------------------------------------------------------------------------------
在二臺三層交換機上配置非直連網段靜態路由：
--------------------------------------------------------------------------------
[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，查看網絡互通情況：
--------------------------------------------------------------------------------
[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
RlP協議在三層交換機上的配置
1.繼續上面的，刪除前面配置的靜態路由。
[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協議：
--------------------------------------------------------------------------------
//交換機B上啟用RIP協議
[S3526A]rip
[S3526A-rip]network 10.1.1.0
[S3526A-rip]network 10.1.2.0
[S3526A-rip]network 10.1.4.0
//交換機B上啟用RIP協議
[S3526B]rip
[S3526B-rip]network 10.1.3.0
[S3526B-rip]network 10.1.4.0
配置完成即可實現網絡互通
查看路由表，查看網絡互通情況：
[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
RIP is turned on
public net VPN-Instance
Checkzero is on Default cost : 1
Summary is on Preference : 100
No peer router
Network :
10.0.0.0
在S3526交換機上運行rip協議時，接口在版本為RIP-2時，缺省使用組播形式傳送報文缺省情況下接收和發送RIP-1報文。而當指定接口RIP版本為RIP-2時，缺省使用組播形式傳送報文
