When applied to MPLS interfaces, the interfaces can be included or excluded in the LSP path
definition by inferring the admin-group name. CSPF will compute a path that satisfies the admin-
group include and exclude constraints.
When applied to IES, VPRN, or network IP interfaces, the interfaces can be included or excluded in
the route next-hop selection by inferring the admin-group name in a route next-hop policy template
applied to an interface or a set of prefixes.
The following provisioning rules are applied to admin group configuration. The system will reject the
creation of an admin-group if it re-uses the same name but with a different group value than an
existing group. The system will also reject the creation of an admin-group if it re-uses the same group
value but with a different name than an existing group.
It should be noted that only the admin groups 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. IES
and VPRN interfaces do not have their attributes advertised in TE TLVs.
Parameters

Description
This command configures the admin group membership of an interface. The user can apply admin
groups to an IES, VPRN, network IP, or MPLS interface.
Each single operation of the admin-group command allows a maximum of five (5) groups to be
specified at a time. However, a maximum of 32 groups can be added to a given interface through
multiple operations. Once an admin group is bound to one or more interface, its value cannot be
changed until all bindings are removed.
The configured admin-group membership will be applied in all levels/areas the interface is
participating in. The same interface cannot have different memberships in different levels/areas.
It should be noted that only the admin groups 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. IES
and VPRN interfaces do not have their attributes advertised in TE TLVs.
The no form of this command deletes one or more of the admin-group memberships of an interface.
The user can also delete all memberships of an interface by not specifying a group name.
