Re: [mpls] 答复: poll on draft-boutros-mpls-lsp-ping-ttl-tlv-02

Hi,

I think this draft does not comply to the MPLS-TP Framework RFC 5921, because it can create overlapping MEGs, which is not allowed by RFC 5921. Based on this RFC only MEPs can generate OAM messages and there can only be 2 MEPs per LSP.

“When considering SPMEs, it is important to consider that the
   following properties apply to all MPLS-TP MEGs (regardless of
   whether they instrument LSPs, SPMEs or MS-PWs):

Busi et al.             Expires June 16, 2011                [Page 15]

Internet-Draft OAM Framework for MPLS-based Transport    December 2010

   o They can be nested but not overlapped, e.g. a MEG may cover a
     path segment of another MEG, and may also include the
     forwarding engine(s) of the node(s) at the edge(s) of the
     path segment. However when MEGs are nested, the MEPs and MIPs
     in the nested MEG are no longer part of the encompassing MEG.

“

Thanks,
Shahram
