Hi, I will attend IETF meeting in Singapore. Would I be granted a chance to present on the proposed draft? If yes, which date and time slot should I expect? Rgds Louis From: Robert Raszuk <robert@raszuk.net> Sent: Tuesday, November 5, 2019 2:55 AM To: Louis Chan <louisc@juniper.net> Cc: idr@ietf. org <idr@ietf.org> Subject: Re: draft-chan-idr-bgp-lu2-00.txt Louis, My point is that VPN label should never be carried in BGP-LU - it does not belong there in transport layer. It is fine to carry a color for it and do the mapping at PEs or ASBRs option B, but not the value. Thx, R.

The following is an example PE1----ABR1-----ABR2-----PE2 PE1 will send the following labels with a color 100 path [2001 13001 801 16], where 2001 - SR label to reach ABR1 13001 - Binding-SID label to reach ABR2. Underlying tunnel type is RSVP-TE 801 - Binding-SID label to reach PE2. Underlying tunnel type is SR-TE 16 - a VPN label ^^^^^^^^^^^^^^^^ Many thx, Robert.
