Abstract:
This draft introduces a hub & spoke multipoint LSP (short for HSMP
LSP), which allows traffic both from root to leaf through P2MP LSP
and also leaf to root along the co-routed reverse path. That means
traffic entering the HSMP LSP from application/customer at the root
node travels downstream, exactly as if it was traveling downstream
along a P2MP LSP to each leaf node, and 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, except that it follows the path of the tree
rather than ordinary unicast to the root.
