In IP Multicasting what is the SPT-bit?

...and what does it mean if it is set or not set?

Is there a document that describes all the flags in the 'sh ip mroute' output?

Hi Friend,

SPT-bit set indicates that packets have been received on the shortest path source tree.

You can look at this link which explain nearly all the flags

The Link provided here is not working. Please post the currently working link here.

Mohammad,

I am not sure if Ankur is still reachable after 8 years (though I hope he is!). Nonetheless, I believe this is the current document:

http://www.cisco.com/c/en/us/td/docs/ios-xml/ios/ipmulti/command/imc-cr-book/imc_s1.html#wp3622554730

Scroll down to Table 24.

Best regards,
Peter
