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 From: mpls-bounces@ietf.org [mailto:mpls-bounces@ietf.org] On Behalf Of wei.hongbo@zte.com.cn Sent: Sunday, December 19, 2010 11:42 PM To: Loa Andersson Cc: Ross Callon; mpls@ietf.org; mpls-bounces@ietf.org Subject: [mpls] 答复: poll on draft-boutros-mpls-lsp-ping-ttl-tlv-02 Yes/Support.
