Hi,
I need some information on how to forward RSVP messages
in MPLS domain
over ATM networks.

Our architecture devided the LER/LSR into two parts:
Switch Part and
MPLS controller part on PC.
PC is connected switch using ATM ENI card. At present we
are
implementing RSVP over windowNT.

My queries are

1. How RSVP control message will be forwarded to nexthop
(LSR). since
RSVP prepares IP packet and forwards to IP layer. IP
layer identifies
Nexthop for destination and forwards to the DataLink
layer (in our case
it ATM or MLSP driver). How ATM driver identifies
correct outgoing
interface and forwards data.

2. Is it prerequisite to provide labels to each FEC in
the routing
table  before using RSVP as label distibution protocol.

Thanks & regards,
