According to the base BGP specification, a BGP speaker that receives
an UPDATE message containing a malformed attribute is required to
reset the session over which the offending attribute was received.
This behavior is undesirable because a session reset would impact not
only routes with the offending attribute but also other valid routes
exchanged over the session. This document partially revises the
error handling for UPDATE messages and provides guidelines for the
authors of documents defining new attributes. Finally, it revises
the error handling procedures for a number of existing attributes.
This document updates error handling for RFCs 1997, 4271, 4360, 4456,
4760, 5543, 5701, and 6368.
This document is a product of the Inter-Domain Routing Working Group of the IETF.
This is now a Proposed Standard.
