Description

Enables you to configure extended administrative groups, represented by a 32-bit value, expanding the number of administrative groups supported in the network beyond just 32. In MPLS traffic engineering, a link can be configured with a set of administrative groups (also known as colors or resource classes). Administrative groups are carried in IGPs (OSPFv2 and IS-IS) as a 32-bit value assigned to each link. By default, Juniper Networks routers interpret this 32-bit value as a bit mask with each bit representing a group. This normally limits each network to a total of 32 distinct administrative groups (value range 0 through 31).

The extended administrative groups configuration accepts a set of interfaces with a corresponding set of extended administrative group names. It converts the names into a set of 32-bit values and propagates this information into the IGP. The extended administrative group values are global and must be identically configured on all the supported routers participating in the network. The domain-wide extended administrative groups database, learned from other routers through IGP flooding, is used by CSPF for path computation.
