Title: Capabilities Advertisement with BGP-4
Author(s): R. Chandra, J. Scudder.
Status: PROPOSED STANDARD
Date: May 2000
Length: 8366
Obsoleted by: RFC3392
Currently BGP-4 [BGP-4] requires that when a BGP speaker receives an OPEN message with one or more unrecognized Optional Parameters, the speaker must terminate BGP peering. This complicates introduction of new capabilities in BGP.
This document defines new Optional Parameter, called Capabilities, that is expected to facilitate introduction of new capabilities in BGP by providing graceful capability advertisement without requiring that BGP peering be terminated.
