Hi WG members,
During last IETF,  Ravinder (Service provider) had a point that it would be nice to have mechanism where network administrator has flexibility to find complete tree view from source. Basically, mtrace does reverse of it where we tracec it from receiver. But his point was , as a service provider it would be good to see complete tree where multicast traffic is flowing.

While thinking in this direction, I thought it might be good to take this question to list and get the input.

  *   One way would be to have mtrace mechanism, which starts from a given point, and goes to each of next hop from where there is PIM join for given (S,G) and then report it back to actual originator.
  *   Can any mechanism from Yang data be used for this purpose ?

Any other thoughts ?

Thanks
Mankamana
