Requirements list from draft-ietf-lsvr-l3dl-00
Layer 3 Discovery and Liveness (L3DL) provides brutally simple
mechanisms for devices to
o Discover unique identities of devices/ports/... on a logical link,
o Run Layer 2 keep-alive messages for session continuity,
o Discover each other's unique endpoint identification,
o Discover mutually supported encapsulations, e.g. IP/MPLS,
o Discover Layer 3 IP and/or MPLS addressing of interfaces of the
encapsulations,
o Enable layer 3 link liveness such as BFD, and finally
o Present these data, using a very restricted profile of a BGP-LS
[RFC7752 <https://tools.ietf.org/html/rfc7752> ] API, to BGP-SPF which
computes the topology and builds
routing and forwarding tables.
If the a authors of this draft would suggest a different list of
requirements,
please just respond to this email.
Cheerily, Sue Hares

Subject: [Idr] Issue 2: Auto-configuration Requirements
IDR WG:
Does IDR think that we should include a generalized auto-discovery protocol
in the IDR WG charter?
If so, should it be for WAN or Data Center or IPRAN topologies (grid/ring)?
LSVR is progressing with Layer 3 liveness in draft-ietf-lsvr-l3dl-00
https://datatracker.ietf.org/doc/draft-ietf-lsvr-l3dl/
LSVR is progressing because IDR did not have a consensus on requirements for
a general Layer 3 liveness protocol in 2018.
This thread is to discuss the requirements for a generalized or
a specific auto-discovery protocol associated with BGP.
My next posts will contain the requirements for LSVR Layer 3 liveness and
draft-xu-idr-neighbor-autodiscovery requirements
