    abstract =  {The BGP specification mandates a maximum BGP message size of 4096 octets. As BGP is extended to support newer AFI/SAFIs, there is a need to extend the maximum message size beyond 4096 octets. This document updates the BGP specification {[}RFC4271{]} by providing an extension to BGP to extend its current message size from 4096 octets to 65535 octets.},
