Traceroute but Cant Ping

Will like to share that am able to traceroute with specfic IP but cant ping is there any bug in router. There is no access list levied on any destined or originated host.

In below post am able to reach the destined router even that router able to reach but why cant i ping?

R1#traceroute 192.168.2.1

Type escape sequence to abort.

Tracing the route to 192.168.2.1

VRF info: (vrf in name/id, vrf out name/id)

  1 10.1.1.17 0 msec 0 msec 4 msec

  2 10.1.1.34 32 msec *  32 msec

R1#ping 192.168.2.1     

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 192.168.2.1, timeout is 2 seconds:

.....

Success rate is 0 percent (0/5)

R1#sh run | i 192.168.2.0

ip route 192.168.2.0 255.255.255.0 10.1.1.17

There is no vrf defined

Hello

The router may be prohibiting Icmp (ping)

Hi Amit,

Do 'debug IP icmp' on the source and destination router will help you find the problem.

Hi

Ping using Source Interface or use extended Ping

In addition to what others have stated, also make sure the 192.168.2.0/24 subnet has a route to get back here. Sourcing the ping from a subnet that the 192 subnet knows about could resolve the issue....

Re: Traceroute but Cant Ping

Hi Amit,
This is something I learned on a CCNP course recently, Traceroute actually uses UDP not ICMP on certain Unix like systems. Worth checking if you've got an access list preventing this.
Cheers
