RIP 選徑規劃及測試

1、PE及CE有兩條LINK
2、跑RIP
3、有分DATA及VOICE網段 (192.168.2.0 data,192.168.3.0 voice)
4、平常DATA跑第一條，VOICE跑第二條
5、斷第一條時，DATA需能跑到第二條
6、斷第二條線，VOICE不需跑到第一條

測試：斷第一條
     172.31.0.0/30 is subnetted, 2 subnets
C       172.31.0.0 is directly connected, FastEthernet0/0
C       172.31.0.4 is directly connected, FastEthernet0/1
R    192.168.2.0/24 [120/4] via 172.31.0.6, 00:00:17, FastEthernet0/1
R    192.168.3.0/24 [120/1] via 172.31.0.6, 00:00:17, FastEthernet0/1

測試：斷第二條
     172.31.0.0/30 is subnetted, 2 subnets
C       172.31.0.0 is directly connected, FastEthernet0/0
C       172.31.0.4 is directly connected, FastEthernet0/1
R    192.168.2.0/24 [120/1] via 172.31.0.2, 00:00:10, FastEthernet0/0

測試：把兩條線都拉起來
     172.31.0.0/30 is subnetted, 2 subnets
C       172.31.0.0 is directly connected, FastEthernet0/0
C       172.31.0.4 is directly connected, FastEthernet0/1
R    192.168.2.0/24 [120/1] via 172.31.0.2, 00:00:02, FastEthernet0/0
R    192.168.3.0/24 [120/1] via 172.31.0.6, 00:00:02, FastEthernet0/1

均符合需求
