Matthew - it would be added to WGLC since WG thinks this is mature document to
moce forward. Sussan Hares - Do i have other drafts in IDR which needed to be
WGLC at same time ? Matthew - its good point, we had something similar issue in
BESS, so it would be good if we take care of all cross reference. Stephane -
There are few drafts which have normative reference in this document, it has
     reference to EVPN FXC draft. .
Ketan -  Reference was left over in error . This document does not have
dependency on any IDR document. it has dependency on SR network programming
which is in Spring and AD evaluation. Stephane - please remove reference to FXC
Gaurav - it would be removed. Susan - if you have any other draft which would
help in deployment, please let me know.

- 0th version of draft, more discussion is needed in this topic from WG.
Jorge -  slides talks about EVPN, IPvpn and draft (section 2.1 ) its mentioning
VPLS too Wen - yes, it's applicable for VPLS too . Needs more clarification.
Jorge - can this happen with VPLS too Wen - If VPLS supports Active Standby ,
it may. will clarify more. Jorge - EVPN case it would be good to add more
detail how it would be handling multicast traffic. Ali - instead of using FRR
label, use implicitly instead of explicitly Wen - if same label is used, PE1
sends FRR traffic to PE2. and if PE1 uses VPN label from PE2 it would not have
way to determine whether its FRR traffic or remote .
