Re: [Idr] I-D Action: draft-ietf-idr-bgpls-segment-routing-epe-17.txt

Hi Sue,

As discussed in the context of the draft-ietf-idr-bgp-ls-segment-routing-ext, this EPE draft also draws on both the BGP-LS security model in RFC7752 and the SR Security model in RFC8402.

IMO this sufficiently covers the security consideration for this BGP-LS extension and I request you to progress this draft further. 

As discussed earlier, we can evaluate RFC7752 from security perspective and I can help with addressing them via an update or a bis, as necessary.

Thanks,
Ketan

Ketan: 

I do not see any reference to a revised RFC7752 in the security section of
this draft.   

If you agree we need a revised RFC7752 draft, please add this text to the security section.  

"RFC7752 security considerations may need to be expanded to cover the
extensions in this draft.   The need to extend the RFC7752 security is
common to many drafts that utilize BGP-LS defined in  RFC7752 so this work is being undertaken in an RFC7752bis rather than this draft."  

If you add this, I can start the 1 week review on text.  

Cheerily,  Sue

Abstract:
   Segment Routing (SR) leverages source routing.  A node steers a
   packet through a controlled set of instructions, called segments, by
   prepending the packet with an SR header.  A segment can represent any
   instruction, topological or service-based.  SR segments allow
   steering a flow through any topological path and service chain while
   maintaining per-flow state only at the ingress node of the SR domain.

   This document describes an extension to BGP Link State (BGP-LS) for
   advertisement of BGP Peering Segments along with their BGP peering
   node information so that efficient BGP Egress Peer Engineering (EPE)
   policies and strategies can be computed based on Segment Routing.
