relative-metric [offset] — the shortest IGP cost between the endpoints of the LSP plus
the configured offset, instead of the LSP operational metric returned by MPLS, is
used when calculating the cost of prefix resolved to this LSP. The offset parameter
is optional. If the relative-metric option is enabled without specifying the offset
parameter value, a value of 0 is used.
Values –10 to +10
include
Syntax [no] include group-name [group-name...(up to 5max)]
Context config>router>mpls>lsp
config>router>mpls>lsp>primary
config>router>mpls>lsp>secondary
config>router>mpls>lsp-template
Description This command specifies the admin groups to be included when an LSP is set up. Up to 5
groups per operation can be specified, and up to 32 maximum.
The no form of the command deletes the specified groups in the specified context.
Default no include
Parameters group-name — specifies admin groups to be included when an LSP is set up
least-fill
Syntax [no] least-fill
Context config>router>mpls>lsp
config>router>mpls>lsp-template
Description This command enables the use of the least-fill path selection method for the computation of
the path of this LSP.
When MPLS requests the computation of a path for this LSP, CSPF finds all equal-cost
shortest paths that satisfy the constraints of this path. Then, CSPF identifies the single link in
each of these paths that has the least available bandwidth as a percentage of its maximum
reservable bandwidth. It then selects the path that has the highest percentage available
bandwidth. CSPF identifies the least-available bandwidth link in each equal-cost path after it
has accounted for the bandwidth of the new requested path of this LSP.
CSPF applies the least-fill path selection method to all requests for a path, primary and
secondary, of an LSP for which this option is enabled. The bandwidth of the path can be any
value, including zero.
