Usage Guideline DXS-3600 Series 10GbE Layer 2/3 Switch CLI Reference Guide The path vector value is valid with the loop detection of the LDP instance enabled. If the LDR ID number that is in the path vector list of the label mapping message or the label request message of LDP is greater than the configured value, it is deemed that a loop occurs. Example This example shows how to configure the maximum path vector to 30. DXS-3600-32S#configure terminal DXS-3600-32S(config)# mpls label protocol ldp DXS-3600-32S(config-mpls-router)# mpls ldp max-path-vector 30 38-25 explicit-null This command is used to advertise an Explicit Null label in situations where it would normally advertise an Implicit Null label. Use the no form of this command to restore the default value. explicit-null no explicit-null Parameters Default Command Mode Command Default Level Usage Guideline None. Egress LSR advertise Implicit NULL label. MPLS Router Configuration Mode. Level: 15. This command is used to configure LDP Penultimate Hop Popping (PHP) behavior. If the LSR is set to egress and the advertise label is an Implicit Null label, the upstream will do Penultimate Hop Popping. If the label distributed to Penultimate Hop is set to the Explicit NULL label, the Penultimate Hop won't pop it. Example This example shows how to configure the egress LSR advertise Explicit NULL label.

Use the no form of this command to restore the default value. md5 authentication no md5 authentication Parameters Default Command Mode Command Default Level None. By default, a peer has no password. MPLS Router Configuration Mode. Level: 15. 357
