dst/src routing drafts (for IETF-91 rtgwg)

[David Lamparter <[e-mail]>]

Hi rtgwg,


freshly submitted & soliciting for feedback are the following drafts:
https://datatracker.ietf.org/doc/draft-lamparter-rtgwg-routing-extra-qualifiers/?include_text=1
https://datatracker.ietf.org/doc/draft-lamparter-rtgwg-dst-src-routing/?include_text=1

These are distilled version of the SADR stuff that has been coming in
from homenet; they describe the hop-by-hop forwarding behaviour
independent of the dynamic routing protocol du jour.  The first one
describes general considerations of adding things ("extra qualifiers")
to destination longest-match, the second one does the specifics for
source match.  They're derived from baker-ipv6-isis-dst-src-routing, and
are essentially write-ups of e-mail threads with Fred.  (Thanks!)

These are -00, so there's a lot of things to be fixed still (I'm not
even sure whether this should be 2 drafts or 1, and some bits should be
moved from -dst-src to -extra-qualifiers if it stays separate.)

I believe rtgwg is the "best" wg for this, looking at the charter this
fits "Enhancements to hop-by-hop distributed routing", though admittedly
it's neither FRR nor LFA.  I'll happily accept a redirect to another wg
(6man? homenet?) if that's deemed more appropriate.

Last but not least, I'd like to request a slot at the IETF 91 rtgwg
meeting to present these drafts.

Cheers & Thanks in advance for feedback,


-David
