Hello folks

in the draft, given that AS#RT# froms a NLRI,

a. Is it possible to have only the AS#RT#s avaliable
on a node and based on the fact that someone does an
import of that RT#, the prefixes should be fetched?
(that is we only send AS#RT# to peers via BGP and when
group membership/VPN membership is signaled, the
prefixes are imported)

b. If (a) is not feasable for whatever reasons  (like
time to fetch prefixes etc), and assuming that
AS#RT#prefix# are all present on the peer, can we
assume that only when a peer of the node imports a
particular AS#RT#, will the corresponding forwarding
element/label be inserted in the FIB?

In other words, other than the benefits of TE from
RSVP-TE, can a or b be used to setup signaled LSPs?
