Hi Lizhong,
I think one possible application for HSMP LSPs is to reduce the overall broadcast/multicast utilization on a VPLS. In current VPLS implementations with a full mesh of P2P LSPs between PEs, broadcast, multicast and unknown traffic are not efficiently propagated on the physical links between PEs and Ps. In the VPLS implementation scenario with HSMP LSPs, each PE signals a HSMP LSP with itself as a root to all other PEs in the VPLS. Thereafter, all broadcast/multicast/unknown traffic from this PE will use this HSMP LSP. Unicast traffic from a particular PE (e.g. PE1) to another PE (e.g. PE2) will be sent from leaf to root using the HSMP LSP where PE2 is the root. This simplifies the VPLS implementation by: - Reducing traffic utilization from broadcast, multicast and unknown traffic - Reducing the total number of LSPs maintained by each PE (i.e. instead of requiring a full mesh of LSPs, now only require one HSMP LSP per PE). This is similar to the idea expressed in draft-key-l2vpn-etree-frwk-03.txt (in a more general sense). What do you think? Would HSMP LSP be suitable for this?
