用ping命令检查每段链路旳互通性,以R1为例:
R1#ping source
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to , timeout is 2 seconds:
Packet sent with a source address of
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 544/667/744 ms
R1#ping source
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to , timeout is 2 seconds:
Packet sent with a source address of
.....
Success rate is 0 percent (0/5)
可以看到R1与R3路由连通但与R4未连通。这是由于R1与R3属于同一区域(即同一子网),R1与R4属于同一区域;而此前只加载了内部网关合同而未加载外部网关合同,因此区域内部路由连通,但不同区域间路由不连通。
MPLS配备
通过mpls label protocol ldp使MPLS域内各路由器启动ldp 合同
通过mpls ip 使MPLS域内各路由器区域内部接口下启动mpls
测试
(1)查看标签绑定表
R1#show mpls ip binding
