MPLS Interface Commands
interface
Syntax [no] interface ip-int-name
Context config>router>mpls
Description This command specifies MPLS protocol support on an IP interface. No MPLS commands are
executed on an IP interface where MPLS is not enabled. An MPLS interface must be explicitly
enabled (no shutdown).
The no form of this command deletes all MPLS commands such as label-map which are defined
under the interface. The MPLS interface must be shutdown first in order to delete the interface
definition. If the interface is not shutdown, the no interface ip-int-name command does nothing
except issue a warning message on the console indicating that the interface is administratively up.
Default shutdown
Parameters ip-int-name — The name of the network IP interface. An interface name cannot be in the form of an
IP address. If the string contains special characters (#, $, spaces, etc.), the entire string must be
enclosed within double quotes.
Values 1 to 32 alphanumeric characters.
admin-group
Syntax [no] admin-group group-name [group-name...(up to 5 max)]
Context config>router>mpls>interface
Description This command defines admin groups that this interface supports.
This information is advertised as part of OSPF and IS-IS to help CSPF compute constrained LSPs
that must include or exclude certain admin groups. An MPLS interface is assumed to belong to all
the admin groups unless the ’admin-group’ command is issued under the interface config. Once an
’admin-group’ command is issued the interface is assumed to belong to only the specifically listed
groups for that command.
Each single operation of the admin-group command allows a maximum of 5 groups to be specified at
a time. However, a maximum of 32 groups can be specified per inteface through multiple operations.
Default no admin-group
Parameters group-name — Name of the group. The group names should be the same across all routers in the
MPLS domain.
