Re: Multicast Shared Tree Characteristics

The slide in PPT mentioned as below:

Shared tree is good for :
- Environments where most of the shared tree is the same as the source tree

I believe the meaning can be as follows:
For most of the paths, from Source S to receivers R1, R2 ...., Rn, the paths
should be same as source Tree. So that it avoids sub-optimal paths.

If you see the previous slides,
The paths from S to R1/R2 are different for source and shared trees. So in
this case, shared tree may not be good.

Thanks,
Srinivas
