Susan Hares:

This draft under this usage case  
 1) Goes against the RFC 4456 requirement for a full distribution of
routes between Route Reflectors in IBGP mesh  
 2) specifies transitive optional Path Attribute (D-PATH) without an
Open Capability limitation, and  
 3) specifies changes to RFC4271 without an open Capability limitation.

Jorge:

*   discussion among authros are in progress
*   issues which were raised being already addressed for safi-1 and
    authors would work with chairs to make progress.

draft-rabnic-bess-evpn-mcast-eeg-00

*   work is based on gap in existing specs in WG.
*   waiting for working group feedback
*   draft-wang-bess-sbfd-discriminator
*   new co-author added
*   more cases added from previous version
*   WG adoption requested
*   Ketan : is this expansion for all AFI/SAFI ?
*   Gerg : yes, this is to make more generic. using existing attributes
    but procedures are changed.
*   Ketan : this is optional transitive, there have been discussion in
    IDR about this. it may be good to check in IDR to prevent
    information being leaked.
*   Greg : will take this input and take feedback from IED
*   Jeffery : Ketan points are correct. IDR general practice is to
    provide detail about how attributes can lead to trouble. Optional
    transitive may be wrong way to do it with security concern.
*   Greg : to mitigate security issue is to use source IP so that
    reflector can verify it.
*   Gyan : is this for EVPN or L3VPN and mVPN as well ? it may be good
    to say its specific to IP-VPN.
*   Greg : clarification would be added .
*   Ketan : follow up on Jeff comment, if putting security considiration
    is good enough.
*   Greg : will have offline discussion.
*   Jie Dong: Some clarification may be good about where to use this and
    have discussion with IDR.
