Hi,

what happen when we give ping 0.0.0.0 .Also i tried to ping loopback address 127.0.0.1 but it is returning as Success rate is 0 percent.

Can anyone throw light on this.

Thanks,

Vijay

you shouldn't be able to ping 0.0.0.0. That is the statement pointing to a default gateway. Also 127.0.0.1 is used for hosts and not routers, if the router doesn't have a route to that address then you won't get a reply.

Hi ,

when I tried ping 0.0.0.0 (from for e.g. 10.1.1.1) it displays:

Sending 5, 100-byte ICMP Echos to 0.0.0.0, timeout is 2 seconds:

Reply to request 0 from 10.1.1.3, 20 ms

Reply to request 1 from 10.1.1.3, 20 ms

Reply to request 2 from 10.1.1.3, 32 ms

Reply to request 3 from 10.1.1.3, 20 ms

Reply to request 4 from 10.1.1.3, 20 ms

where 10.1.1.3 is directly connected neighbor.The routing shows like this:

10.0.0.0/24 is subnetted, 2 subnets

C 10.1.1.0 is directly connected, Ethernet0/0

C 10.1.0.0 is directly connected, Serial1/0

no default static is configured.

Thanks,

Vijay
