You can place individual interfaces into administrative groups. For example, you can define a group named gold and assign high-bandwidth interfaces to it. When a device calculates the path for an LSP, it can take into account the administrative group to which a interface belongs. You can configure up to 32 administrative groups. By default, an interface does not belong to any administrative groups.

Administrative groups are in the range from 0 through 31. You can set an administrative group by name and number. To set an administrative group by name, first create a name for the group and associate the name with an administrative group number.
