This document summarizes two Internet-Drafts presented at the IETF GROW working group meeting: 1) draft-ietf-grow-bmp-tlv proposes adding support for TLVs in BMP Route Monitoring and Peer Down messages to provide backwards compatibility when adding new message types. It received positive feedback and minor fixes were processed. 2) draft-lucente-grow-bmp-tlv-ebit addresses the need for vendors to define proprietary information elements by proposing the use of an E-bit flag for experimental TLVs. It received feedback that experimental TLVs should use the E-bit instead of specific number ranges, and the authors believe the E-bit could also apply to other fields like stats types

2. draft-ietf-grow-bmp-tlv
• Problem statement:
§ Not all BMP message types support TLVs
• Ideas in the draft:
§ Support TLVs in Route Monitoring
§ Support TLVs in Peer Down
§ Bump version for backwards compatibility

3. • Added wire format example (thanks Luuk!)
• Processed feedback
• Constellation of minor fixes
Since IETF115 / draft-ietf-grow-bmp-tlv-10

4. • Move the BGP PDU into a TLV
• Stateless parsing TLVs:
o Remove, ADD-PATH becomes a bit in Peers Flag
• Bump version to 4 or use a new Message Type:
o Authors prefer to keep bumping version
o WG Chairs? Any opinion?

6. Problem statement
“Vendors need the ability to define proprietary Information Elements,
because, for example, they are delivering a pre-standards product, or
the Information Element is in some way commercially sensitive”

7. • Processed feedback
Since IETF115 / draft-ietf-grow-bmp-tlv-ebit-01

8. • 65531-65534 are for experimental use for Information TLVs
o E-bit should be used for experimental use instead
• Should E-bit be applicable to other pieces too? Ie. Stats Types?
o Authors believe so. Feedback?
