Re: RE: draft-llsyang-rtgwg-dst-src-routing-00

Dear Les, 

We see that src/dst routing is more and more important in recent years, for better security (https://www.ietf.org/archive/id/draft-li-savnet-intra-domain-problem-statement-00.txt)
and flexible policy (https://www.ietf.org/archive/id/draft-xu-spring-segment-twod-ip-routing-01.txt). 

> What routing protocols do you see as still relevant here?
OSPF, IS-IS, BGP, etc. They can all be upgraded to support src/dst routing.
