Technical Summary
This draft introduces a hub & spoke multipoint (HSMP) Label Switched
Path (LSP), which allows traffic both from root to leaf through
point-to-multipoint (P2MP) LSP and also leaf to root along the
reverse path. That means traffic entering the HSMP LSP from
application/customer at the root node travels downstream to each leaf
node, exactly as if it is travelling downstream along a P2MP LSP to
each leaf node. Upstream traffic entering the HSMP LSP at any leaf
node travels upstream along the tree to the root, as if it is unicast
to the root. The communication among the leaf nodes are not allowed.
