思科路由器数据长度较大时ping不通
我在做IP分片的实验,链路上最小的MTU是700,我发送长度为800的数据包时显示是可以ping通的:R1#ping 192.34.5.1 size 800 source 192.34.4.1
Type escape sequence to abort.
Sending 5, 800-byte ICMP Echos to 192.34.5.1, timeout is 2 seconds:
Packet sent with a source address of 192.34.4.1
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 44/80/200 ms
R1#
但是发送大小为900的数据包时就不通了,显示超时:
R1#ping 192.34.5.1 size 900 source 192.34.4.1
Type escape sequence to abort.
Sending 5, 900-byte ICMP Echos to 192.34.5.1, timeout is 2 seconds:
Packet sent with a source address of 192.34.4.1
.....
Success rate is 0 percent (0/5)
这是什么情况啊,很急很急,在线等。。。 check the routing table on both side! {:6_290:}{:6_290:} {:6_267:}{:6_267:} {:6_268:}{:6_268:}
