MPLS Guide
The association of the optional path group ID is to allow the PCE to determine which
profile ID this path group ID must be used with. One path group ID is allowed per
profile ID. The user can, however, enter the same path group ID with multiple profile
IDs by executing this command multiple times. A maximum of five entries of
path-profile [path-group] can be associated with the same LSP. More details of the
operation of the PCE path profile are provided in the
3.23.4 Configuring SR-TE LSP Label Stack Size
Use the following syntax to configure the maximum number of labels that the ingress
LER can push for a specific SR-TE LSP:
CLI Syntax:
This command allows the user to reduce the SR-TE LSP label stack size by
accounting for additional transport (including entropy), service, and other labels
when packets are forwarded in a particular context. See
information about label stack size requirements in various forwarding contexts. If the
CSPF on the PCE or the router's hop-to-label translation cannot find a path that
meets the maximum SR label stack, the SR-TE LSP will remain on its current path
or will remain down if it has no path. The range is 1 to 11 labels with a default value
of 6.
3.23.5 Configuring Adjacency SID Parameters
Configure the adjacency hold timer for the LFA or remote LFA backup next hop of an
adjacency SID.
Use the following syntax to configure the length time that LTN or ILM records of an
adjacency SID are kept:
CLI Syntax:
