Abstract:
This draft introduces a hub & spoke multipoint LSP (or HSMP LSP for
short), 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 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, and strictly
follows the downstream path of the tree rather than routing protocol
based unicast path to the root.
