Regarding Traceroute

Praveen,

Please review the PDF.

http://www.cisco.com/application/pdf/paws/13730/ext_ping_trace.pdf

My reading tells me that 30 is an arbitrary number, I guess they (cisco programmers) figured after 30 hops you've got other problems.

If you still have problems understanding what traceroute is about then you may want to rephrase your question to highlight what you'd really like to know.

Regarding Traceroute

Hi,

IMHO, traceroute is NOT limited to  maximum of 30 hops.

It's just a default value on Cisco routers.

See:

Router1# trace ip 10.10.10.10 ttl 1 ?

<1-255>  maximum ttl

So if you want, you can trace up to 255 hops.

The same in MS Windows:

C:\Documents and Settings\mk>tracert -h 255 www.cisco.com

....

HTH,

Milan
