display ip routing-table ====查看路由表
Route Flags: R – relay, D – download to fib
——————————————————————————
Routing Tables: Public
Destinations : 11 Routes : 11

Destination/Mask Proto Pre Cost Flags NextHop Interface
1.1.1.1/32 Direct 0 0 D 127.0.0.1 LoopBack0
127.0.0.0/8 Direct 0 0 D 127.0.0.1 InLoopBack0

202.100.1.0/24 Direct 0 0 D 202.100.1.1 GigabitEthernet0

二、配置静态路由

[R1]ip route-static 3.3.3.3 255.255.255.255 202.100.2.3 ===添加静态路由
[R1]ip route-static 202.100.3.0 255.255.255.0 202.100.2.3

[R1]display ip routing-table =====Static代表静态路由，60代表静态路由优先级
Route Flags: R – relay, D – download to fib
——————————————————————————
Routing Tables: Public
Destinations : 13 Routes : 13
Destination/Mask Proto Pre Cost Flags NextHop Interface
1.1.1.1/32 Direct 0 0 D 127.0.0.1 LoopBack0
3.3.3.3/32 Static 60 0 RD 202.100.2.3 GigabitEthernet0
ping -c 1 3.3.3.3

Reply from 202.100.3.3: bytes=56 Sequence=1 ttl=255 time=10 ms

三、配置浮动路由用于备份

配置备份静态路由，当R1与R3之间链路出现故障时，可走R2。
[R2]ip route-static 3.3.3.3 255.255.255.255 202.100.3.3
[R1]ip route-static 202.100.3.0 24 202.100.1.2 preference 80
[R1]ip route-static 3.3.3.3 32 202.100.1.2 preference 80

[R3]ip route-static 202.100.1.0 255.255.255.0 202.100.3.2

[R1]tracert 202.100.3.3
traceroute to 202.100.3.3(202.100.3.3), max hops: 30 ,packet length: 40,press CTRL_C to break
1 202.100.2.3 10 ms 10 ms 20 ms

[R1]tracert 3.3.3.3
traceroute to 3.3.3.3(3.3.3.3), max hops: 30 ,packet length: 40,press CTRL_C to break
1 202.100.2.3 20 ms 10 ms 20 ms

[R1]int g0/0/2
[R1-GigabitEthernet0/0/2]shutdown

[R1]display ip routing-table
Route Flags: R – relay, D – download to fib
——————————————————————————
Routing Tables: Public
Destinations : 10 Routes : 10
3.3.3.3/32 Static 80 0 RD 202.100.1.2 GigabitEthernet0/0/1
202.100.3.0/24 Static 80 0 RD 202.100.1.2 GigabitEthernet0/0/1

[R1]tracert 3.3.3.3
1 202.100.1.2 20 ms 1 ms 10 ms
2 202.100.3.3 20 ms 10 ms 20 ms

[R1]tracert 202.100.3.3
1 202.100.1.2 1 ms 10 ms 10 ms
2 202.100.3.3 20 ms 20 ms 20 ms

[R1]interface g0/0/2
[R1-GigabitEthernet0/0/2]undo shutdown (注：华为设备中no掉配置命令undo) 此处敲restart也可以
May 12 2014 22:58:05-05:13 R1 %%01IFPDT/4/IF_STATE(l)[6]:Interface GigabitEtherne
t0/0/2 has turned into UP state.

[R2]ip route-static 0.0.0.0 0.0.0.0 202.100.3.3 ====添加默认路由
[R2]ping 202.100.2.1
PING 202.100.2.1: 56 data bytes, press CTRL_C to break
Reply from 202.100.2.1: bytes=56 Sequence=1 ttl=254 time=10 ms
Reply from 202.100.2.1: bytes=56 Sequence=5 ttl=254 time=30 ms

四、配置默认路由

配置备份默认路由，当R2与R3之间链路出现故障时，可走R1。
[R2]ip route-static 0.0.0.0 0.0.0.0 202.100.1.1 preference 80
[R3]ip route-static 0.0.0.0 0.0.0.0 202.100.2.1 preference 80

[R2]int g0/0/0
[R2-GigabitEthernet0/0/0]shut
[R2-GigabitEthernet0/0/0]

[R2]tracert 202.100.2.3
traceroute to 202.100.2.3(202.100.2.3), max hops: 30 ,packet length: 40,press CTRL_C to break
1 202.100.1.1 10 ms 10 ms 10 ms
2 202.100.2.3 20 ms 20 ms 10 ms
