The MPLS WG Archive[Date Prev][Date Next][Thread Prev][Thread Next] [Date Index][Thread Index][Author Index][Subject Index] [mpls] Some questions about draft-ietf-mpls-ldp-p2mp-01, thank you!
2.3.1.1. Determining one's 'upstream LSR' A node Z that is part of P2MP LSP <X, Y> determines the LDP peer U which lies on the best path from Z to the root node X. If there are more than one such LDP peers, only one of them is picked. U is Z's "Upstream LSR" for <X, Y>. Which is the "best path" for Z. Two ways can determine the best path. 1. Z can look up the normal "route table", and get the best path according the route.(The route table may be generated by OSPF, ISIS, RIP, or even OSPF-TE) 2. Z can get the best path according the multicast table (this table may be generated by various multicast routing protocols), and the P2MP LSP or MP2MP LSP will only work on the routers that support corresponding multicast routing protocols. The two ways are not compatiable, and the two P2MP LSPs or MP2MP LSPs are defferent. Maybe this draft should describe the two ways, and specify one way or both the two ways. The best path selection problem should be solved. -------------------------------------------------------- ZTE Information Security Notice: The information contained in this mail is solely property of the sender's organization.
