Re: [Bier] WGLC: draft-ietf-bier-php

All,

yes, support.

I have one thought that possibly don't need to have an impact on
progressing this draft.

If you think of the p2mp forwarding tree in bier as a p2mp LSP,
it seems to me that the LSP setup by this draft ends on penultimate
node (which is kind of an oxymoron). The ultimate node is also the
node th do the PHP, which would make it UHP. If the LSP ends on a node
that is the ultimate node.

For example in MPLS the LSP ends on the ultimate node, while the
pen-ultimate node does the PHP.

It would also be interesting to know how PCE does this. Dhruv?

As I said, don't let thgis stop progressing this draft, but we
maybe should sit down and and come with a unified way of using
the concepts.
