Commands for checking the communication


8/9

PING command is used

In topology if we want to commumicate with from PC0 to PC7then the following

Command is used

ping 192.167.25.3

now reply will come as

Pinging 192.167.25.3 with 32 bytes of data:

Reply from 192.167.25.3: bytes=32 time=172ms TTL=124

Reply from 192.167.25.3: bytes=32 time=219ms TTL=124Reply from 192.167.25.3: bytes=32 time=188ms TTL=124Reply from 192.167.25.3: bytes=32 time=158ms TTL=124

Ping statistics for 192.167.25.3:Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),

Approximate round trip times in milli-seconds:Minimum = 158ms, Maximum = 219ms, Average =

184ms

This means every route of this topology is working andreplying back with no loss of

packets.If there is some

problem in the network or configuration the message will beof ICMP Group i.e

i)Request timed out .

ii)Destination host unreachable.

Problem may be in


9/9

a)Routing is not done properly .

b)Router interfaces are not set properly.
