Large BGP Communities


The Large BGP Communities approach comes from a long and rich lineage of IETF proposals. These proposals are called IETF Internet-Drafts. Unlike its predecessors, Large BGP Communities have been designed as simple as possible, but no simpler.

With Large BGP Communities, network operators can continue to build upon well established practises in the tradition of RFC 1997.

Vendors only need to implement an unambiguous fixed length BGP attribute. For any implementation assistance contact the team at:

Predecessors such as flexible-bgp-communities and wide-bgp-communities surfaced respectively 12 and 6 years ago, but failed to gain traction with any vendor due to their implementation complexity.
