The MPLS WG Archive[Date Prev][Date Next][Thread Prev][Thread Next] [Date Index][Thread Index][Author Index][Subject Index] About the Non-compliant Routers in MPLS PING and MPLSTRACEROUTE(Y.17fw)
In appendix 4: Diagnostic tools,it states that, When we execute MPLS PING or MPLS TRACEROUTE, If the egress LSR for the FEC Stack being pinged does not support MPLS ping, then no LSP-PING reply will be sent. If in trace mode, a transit LSR does not support MPLS ping, then no reply will be forthcoming from that LSR for some TTL, say n. Under such circumstance,how I distinguish the scenario that there is something wrong along the LSP from the scenario that there is Non-compliant Routes along the LSP .i.e. if the PING dosen't work,how do I know if it is because the existence of the non-compliant Routes? What is your consideration? Sincerely Yours Defeng Li Huawei Technologies +86-10-82882343 lidefeng@huawei.com
