Hi,

I have one small question on draft-yasukawa-mpls-rsvp-p2mp-01.txt.

Can you confirm whether the Original and Modified TEROs in section 6.3
(sender initiated pruning) are correct?

>From section 4.6.1.1, I would expect the original TERO
{A(0,1),B(1,1),C(1,1),D(1,1),E(2,1),F(3,1),G(3,1),H(3,1)} to correspond to
the following tree:

       A
       |
    +--+--+
    |  |  |
    B  C  D
          |
          E
          |
       +--+--+
       |  |  |
       F  G  H

However, from the example in 6.1, I would expect the modified TERO
{A(0,2),B(1,2),C(1,1),D(1,1),E(2,2),H(3,1)} to correspond to:

       A
       |
    +--+--+
    |  |  |
    B  C  D
    |
    E
    |
    H

Have I missed something, or should the original TERO for this example
actually be {A(0,1),B(1,1),E(2,1),F(3,1),G(3,1),H(3,1),C(1,1),D(1,1)},
corresponding to:

       A
       |
    +--+--+
    |  |  |
    B  C  D
    |
    E
    |
 +--+--+
 |  |  |
 F  G  H

Regards,

Ed
