no md5 authentication
Usage Guideline
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
Parameters
None.
Default
Egress LSR advertise Implicit NULL label.
Command Mode
MPLS Router Configuration Mode.
Command Default Level
Level: 15.
Usage Guideline
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.
DXS-3600-32S#configure terminal
DXS-3600-32S(config)# mpls label protocol ldp
DXS-3600-32S(config-mpls-router)#explicit-null
Parameters
None.
Default
