> 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.
