玩转-单臂路由!!!

玩转-单臂路由!!!

ITAA学员设计实验 www.one-tom.com/bbs
应某新学员要求,今仿真了一个单臂路由实验台,希望对其有所帮助。另申请加入等级一实验手册------交换部分,丰富其内容。实验拓扑如下:




单臂路由,实验目的:
2600单接口,通过逻辑上的子接口,实现VLAN间通讯;

步骤如下:
< 1 > 我们拿三台路由器,仿真每个VLAN里的一台主机;

< 2 >
在Cisco2900 上划分三个VLAN,分别为:VLAN 10 、20 、30;
这个时候不同VLAN里的主机是无法通讯的,想通讯就得接入路由设备;

< 3 > 2600 只有一个以太口,我们可以通过划分子接口,来实现目的;
值得注意的是:此以太口必须运行在Trunk模式,且封装相同的Trunk协议 和对应的VLAN号;这样才能正确起地址;

< 4 >
这时把每个VLAN内部主机的 缺省网关指向 2600对应的子接口地址,OK!


配置如下:
R1、R2、R3 配置就不用说了,配个地址,no ip routing ,指个网关就好。下面重点看一下2600和2900 的配置:

2900
交换机配置如下:

SW-1#vlan database
SW-1(vlan)#vlan 10 name reeper-1
VLAN 10 modified:
Name: reeper-1
SW-1(vlan)#vlan 20 name reeper-2
VLAN 20 modified:
Name: reeper-2
SW-1(vlan)#vlan 30 name reeper-3
VLAN 30 modified:
Name: reeper-3
SW-1(vlan)#exit
APPLY completed.
Exiting....

2600 路由器配置
2600(config)#interface ethernet 0/0

2600(config-subif)#enc dot 20
2600(config-subif)#ip add 172.16.2.254 255.255.255.0
2600(config-subif)#int e0/0.3
2600(config-subif)#enc dot 30
2600(config-subif)#ip add 172.16.3.254 255.255.255.0

2600#sh ip ro
Codes: C - connected, S - static, I - IGRP, R - RIP, M - mobile, B - BGP
D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area
N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2
E1 - OSPF external type 1, E2 - OSPF external type 2, E - EGP
i - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS level-2
ia - IS-IS inter area, * - candidate default, U - per-user static route
o - ODR, P - periodic downloaded static route

Gateway of last resort is not set

172.16.0.0/24 is subnetted, 3 subnets
C 172.16.1.0 is directly connected, Ethernet0/0.1
C 172.16.2.0 is directly connected, Ethernet0/0.2
C 172.16.3.0 is directly connected, Ethernet0/0.3


配置完成,我们做一下测试,在R1---VLAN 10ping VLAN20里的R2,和VLAN 30 R3

R-1#ping 172.16.2.1
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 172.16.2.1, timeout is 2 seconds:
..!!!
Success rate is 60 percent (3/5), round-trip min/avg/max = 4/10/20 ms

R-1#ping 172.16.3.1

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 172.16.3.1, timeout is 2 seconds:
..!!!
Success rate is 60 percent (3/5), round-trip min/avg/max = 4/10/20 ms
还可以做以下扩展,加入 VTP的话 等级一的交换部分的实验就都包括了; 在上个实验加一台交换机, 起Trunk ,相互学习VLAN信息,拓扑如下:




具体实验,希望等级一学员积极参与一下,配置我会跟贴 上来。
