Hi Dhananjay,

On the “Generic BMP TLVs”, what is the tangible benefit that you would see by defining it?

I mean, for sure you would not have to define the same code point in multiple registries -- but that is just like saving some words in a document and some effort to keep the registries sync'd up (i admit that we can be a bit smarter with allocations).

On the other hand, guess you have a generic namespace and per message type namespaces, with the per message type namespaces already populated: what do you do with existing code points. Also probably not many TLVs may apply to message types like Init and Term.

Hello Authors,

This draft requests Timestamp TLV type be assigned from “BMP Route Monitoring TLVs” registry. However, the section below indicates that the timestamp TLV could be included in Peer-Up/Peer-Down messages (since it mentions ‘BMP session going down or up’).


        2.1.1.
        
<https://datatracker.ietf.org/doc/html/draft-younsi-grow-bmp-snts-01#section-2.1.1>Trigger
 Time 
<https://datatracker.ietf.org/doc/html/draft-younsi-grow-bmp-snts-01#name-trigger-time>

The Trigger Time is the timestamp of the event which triggered BMP to report the event. This might be a received message, a BGP peering or a BMP session going down or up, etc.

Should the Timestamp TLV belong to a new “Generic BMP TLVs” registry that has TLVs that could be used in multiple BMP message types? This TLV, in all possibility, can go in messages other than just the Route Monitoring message.
