Introduction The BGP specification [RFC4271] mandates a maximum BGP message size of 4096 octets. As BGP is extended to support newer AFI/SAFIs and newer capabilities (e.g., [I-D.ietf-sidr-bgpsec-overview]), there is a need to extend the maximum message size beyond 4096 octets. This draft provides an extension to BGP to extend its current message size limit from 4096 octets to 65535 octets. 2.

The + BGP Extended Messages have maximum message size of 65535 octets. The smallest message that may be sent consists of a BGP header without a data portion (19 octets).
