While I'm hesitant to consider this a perfect idea due to the fact that there are mechanisms within BGP to make this a non-disrupting event not in such explicit need of notification similar to a shut down event, such as graceful restart, end-of-rib markers etc, there is the possibility of a reset occurring and the BGP session not restoring as intended with a notification from the remote side or indeed a TCP reset should the speaker not be willing/ready to accept the new connection. At which point, it would be good to have the shut down communication message to reference the intended action, reference a contact point etc. I'd support a widening of the draft to include the additional code point (Cease/Administrative Shutdown and Cease/Administrative Reset). Indeed, could not all Cease sub-codes use this method? For instance: 1 Maximum Number of Prefixes Reached The notification could provide a link to a filter update site, or an email address for the NOC to take further actions... Or to indicate whether or not the connection is moved into an error state with no future connections allowed until the error is cleared by an operator. 3 Peer De-configured Likewise, this could be supplemented with a message when the session is being deconfigured and moved to another router. 6 Other Configuration Change This has always been difficult to interpret, and has very recently been something I've been butting up against. A vendor supplied string detailing the exact change mechanism that caused this would be welcome. There is obvious scope-creep at this point, I would like to suggest either the draft considered as-is or to allow all Cease sub-codes to have shutdown communication possible. The rest of the draft itself seems well written, easy to understand, and even unamended would be a welcome addition to the internet operators toolkit. Matthew Walster
