MPLS and RSVP-TE
The no form of this command deletes the association of this interface with one or more of the
admin groups.
Default
no admin-group
Parameters
group-name — specifies the name of the group. The group names should be the same
srlg-group
Syntax
[no] srlg-group group-name [group-name...(up to 5 max)]
Context
config>router>mpls>interface
Description
This command associates an MPLS interface with one or more SRLGs. The SRLG must
already be defined in the config>router>if-attribute context (refer to the 7705 SAR Router
Configuration Guide, "IP Router Command Reference").
Up to five SRLGs can be specified with one command. When an SRLG is bound to one or
more interfaces, its value cannot be changed until all bindings are removed.
When SRLGs are associated with MPLS interfaces, CSPF at an LER will exclude the SRLGs
of interfaces used by the LSP primary path when calculating the route of the secondary path.
CSPF at an LER or LSR will also exclude the SRLGs of the outgoing interface of the primary
LSP path in the calculation of the path of the FRR backup LSP. This provides a path disjoint
between the primary path and the secondary path or FRR backup path of an LSP.
The configured SRLG membership is applied in all levels or areas that the interface is
participating in. The same interface cannot have different memberships in different levels or
areas.
SRLGs bound to an MPLS interface are advertised area-wide in TE link TLVs and sub-TLVs
when the traffic-engineering option is enabled in IS-IS or OSPF.
The no form of this command deletes the association of this interface with one or more of the
SRLGs.
Default
n/a
Parameters
group-name — specifies the name of the SRLG. The group names should be the same
