Compliance statements for these types of documents are funny.  Both of the
additional conditions in the document are MAYs and thus everyone is
compliant. :-)

That said, Juniper implements the 3.1 check against whether a nexthop is
resolvable in a given data plane protocol; e.g. MPLS.  This may be adjusted
using configuration.  (Our "resolution ribs" feature.)

Juniper implements the 3.2 path availability check in several variations,
but not all.  For example, BFD may be used to protect MPLS generated
nexthops for LDP and RSVP.  For IP nexthops distributed via an IGP, the IGP
may be protected using BFD.

It is also worth noting that Juniper has partial support for the
tunnel-encaps draft, particularly in support of specific SR-TE applications.
We are not fully compliant.
