I would like to propose draft-jaufeerally-bgp-lg-cap-00
(https://datatracker.ietf.org/doc/draft-jaufeerally-bgp-lg-cap/) as a
mechanism for in-band dissemination of looking glass endpoints in BGP,
using a new OPEN message capability.
Hi Rayhaan,
what we need from routers is a consistent API endpoint which serves RIB
data, that can be consumed by client apps.
I.e. this should be done using json/xml/etc; it should be available over
over https; it should be accessible via a REST API; it should be aimed
at having a front-end HTTP cache server to implement rate limiting /
limited access control / etc (i.e. remove as much complication from the
router as possible), and the data model should be flexible enough to
handle a variety of different deployment configurations (e.g. ibgp /
ebgp / l3vpn / l2vpn / evpn / ixp route server / etc).
INEX has done this for BIRD (see github.com/inex/birdseye, which
provides both the data model and the LG), but the data model is designed
around constructs which are only available in BIRD, so this isn't really
portable to other BGP stacks. But the principle works, and works well.
