使用GNS3進行子網及路由配置
拓撲圖
一、基本配置
1.R1路由器的基本配置
enable
configure terminal
interface f0/0
ip address 192.168.10.1 255.255.255.224
no shutdown
interface f1/0
ip address 202.100.10.1 255.255.255.252
no shutdown
2.R2路由器的基本配置
enable
configure terminal
interface f0/0
ip address 202.100.10.2 255.255.255.252
no shutdown
interface f1/0
ip address 202.100.20.1 255.255.255.252
no shutdown
3.R3路由器的基本配置
enable
configure terminal
interface f0/0
ip address 192.168.20.1 255.255.255.224
no shutdown
interface f1/0
ip address 202.100.20.2 255.255.255.252
no shutdown
4.VPCS配置
VPCS1:ip 192.168.10.2/27 192.168.10.1
VPCS2:ip 192.168.20.2/27 192.168.20.1
5.連通性測試(失敗,因為路由器上未新增路由)
VPCS1:ping 192.168.20.2
VPCS2:ping 192.168.10.2
二、靜態路由配置(全域性模式下完成)
1、R1靜態路由配置
exit
ip route 0.0.0.0 0.0.0.0 202.100.10.2
2、R2靜態路由配置
exit
ip route 192.168.10.0 255.255.255.224 202.100.10.1
ip route 192.168.20.0 255.255.255.224 202.100.20.2
3、R3靜態路由配置
exit
ip route 0.0.0.0 0.0.0.0 202.100.20.1
4、檢視路由表
1>檢視R1路由器的路由表
R1#show ip route(共有3條路由:2條直連路由,1條靜態預設路由)
C 192.168.10.0/27..........(C為直連路由)
C 202.100.10.0/30.............
S* 0.0.0.0/0.................(S*為靜態預設路由)
2>檢視R2路由器的路由表
R2#show ip route(共有4條路由:2條直連路由,2條靜態路由)
C 202.100.10.0/30..........(C為直連路由)
C 202.100.20.0/30.............
S 192.168.10/27.................(S為靜態路由)
S 192.168.20/27.................(S為靜態路由)
3>檢視R3路由器的路由表
R3#show ip route(共有3條路由:2條直連路由,1條靜態預設路由)
C 192.168.20.0/27..........(C為直連路由)
C 202.100.20.0/30.............
S* 0.0.0.0/0.................(S*為靜態預設路由)
三、連通性測試(成功,所有路由已新增)
VPCS1:ping 192.168.20.2
VPCS2:ping 192.168.10.2
四、路由跟蹤測試
VPCS1:trace 192.168.20.2
VPCS2:trace 192.168.10.2
