I'd like to get back to this point... An end-to-end automated OAM
mechanism over LSP in Y.1711 sounds indeed very interesting. Now I
understand the working return path issue brought forth by LSP_PING. I am
sure this has been discussed in the ITU wg but I am a bit concerned as to
how scalable would this be since for the most cases, these LSPs are
terminated at P/PE devices... If implemented, it may be turned on as
needed basis should some LSP path become chronically unstable ?
