Abstract Abstract
This specification augments "Multiprotocol Extensions for BGP-4" (MP- This specification augments "Multiprotocol Extensions for BGP-4" (MP-
BGP) by proposing a mechanism to facilitate the use of multiple BGP) by proposing a mechanism to facilitate the use of multiple
sessions between a given pair of BGP speakers. Each session is used sessions between a given pair of BGP speakers. Each session is used
to transport routes related by some session-based attribute such as to transport routes related by some session-based attribute such as
AFI/SAFI. This provides an alternative to the MP-BGP approach of AFI/SAFI. This provides an alternative to the MP-BGP approach of
multiplexing all routes onto a single connection. multiplexing all routes onto a single connection.
