Abstract:
The BGP protocol contains number of built in mechanisms which records
information about the routers which have processed a specific piece
of reachability information critical to insuring only loop free paths
are chosen by the protocol. For instance, the AS_PATH, CLUSTER_LIST
and ORIGINATOR_ID attributes carry information designed to insure
permanent routing loops are not formed in the path chosen towards a
particular destination. However, there are no provisions to record
other useful information along the path, metadata about the routers
through which reachability information has passed which can be
helpful to the operator in order to enhance end to end visibility of
the BGP control plane.
In order to solve this problem this document proposes a new single
BGP attribute designed as an generic and extensible container to
carry number of new optional information corresponding to the BGP
speakers given BGP advertisement (or withdraw) message traverses.
