发表: 2006-7月-28 19:47[/td][/tr][tr][td][size=2]实验：浮动静态路由[/size]
[size=2]在看np的高级路由的时候书中有一个浮动静态路由的实验，我用远程的台子做了一下这个实验。[/size]
[size=2]拓扑图[/size]
[size=2] (r2)
/ \
/ ; \
/ ; \
(r1)--------(r3)[/size]
[size=2]r1 s1/0:1.1.1.1/24 s2/0:10.1.1.1/24[/size]
[size=2]r2 s1/0:2.2.2.2/24 s2/0:1.1.1.2/24[/size]
[size=2]r3 s1/0:10.1.1.3/24 s2/0:2.2.2.3/24[/size]
[size=2]配置如下：[/size]
[size=2]r1[/size]
[size=2]hostname 1
!
interface Serial1/0
ip address 1.1.1.1 255.255.255.0
clockrate 64000
!
interface Serial2/0
ip address 10.1.1.1 255.255.255.0
!
ip route 2.0.0.0 255.0.0.0 10.1.1.3[/size]
[size=2]r2[/size]
[size=2]hostname 2
!
interface Serial1/0
ip address 2.2.2.2 255.255.255.0
clockrate 64000
!
interface Serial2/0
ip address 1.1.1.2 255.255.255.0
!
ip route 10.0.0.0 255.0.0.0 1.1.1.1
[color=#660000]ip route 10.0.0.0 255.0.0.0 2.2.2.3 10 /手动添加的一条浮动路由，管理距离为10/[/color][/size]
[size=2]r3[/size]
[size=2]hostname 3
!
interface Serial1/0
ip address 10.1.1.3 255.255.255.0
clockrate 64000
!
interface Serial2/0
ip address 2.2.2.3 255.255.255.0
!
ip classless
ip route 1.0.0.0 255.0.0.0 10.1.1.1[/size]
[size=2]我从r2上ping10.1.1.3,为了更好的看效果我添加了访问控制列表。[/size]
[size=2]r2的路由表:
2#show ip route [/size]
[size=2] 1.0.0.0/24 is subnetted, 1 subnets
C 1.1.1.0 is directly connected, Serial2/0
2.0.0.0/24 is subnetted, 1 subnets
C 2.2.2.0 is directly connected, Serial1/0
S 10.0.0.0/8[color=#330000] [/color][color=#660000][1/0] [/color]via 1.1.1.1
2(config)#access-list 101 permit ip host 1.1.1.2 host 10.1.1.3
2(config)#access-list 101 permit ip any
2#debug ip pac 101
debug输出为:

注意到是从s2/0出去的.[/size]
[size=2]现在我们在r1上把s1/0shutdown掉[/size]
[size=2]r2的路由表:
2#show ip route

S 10.0.0.0/8 [color=#ff0000][10/0] [/color]via 2.2.2.3[/size]
[size=2]r2上的访问控制列表为:
2(config)#access-list 102 permit ip host 1.1.1.2 host 10.1.1.3
2(config)#access-list 102 permit ip any
2#debug ip pac 102
debug输出为:

[size=2]可以看出ping是从s1/0出去的,说明了浮动路由起了作用.[/size]
