Establishing administrative group names
Administrative groups, also known as resource classes or link colors, allow you to assign MPLS-enabled interfaces to various classes.
When a device calculates the path for an LSP, it can take into account the administrative group to which an interface belongs; you can specify which administrative groups the device can include or exclude when making its calculation.
As many as 32 administrative groups can be configured on the device. You can see an administrative group either by its name or its number. Before you can see an administrative group by its name, you must specify a name for the group at the MPLS policy level and associate the name with the number of that administrative group.
To establish an administrative group name, perform the following steps.
- Enable the name of the global administrative group.
vyatta@R1# set protocols mpls-rsvp globals name gold value 30
- Configure the name of the administrative group for the interface.
vyatta@R1# set protocols mpls-rsvp interfaces interface <name> admin-groups gold 30In this example, the administrative group name gold is used with the administrative group number 30. The administrative group number ranges from 0 through 31.
After you associate an administrative group name with a number, you can see it by name when assigning interfaces to the group or including or excluding the group from LSP calculations.
