:>LSP. Also, all the Edge Routers in the MPLS domain are preconfigured.
:>So the LSPs are created from the Ingress point to every Edge Router.
:>Now the data packet for the destination outside the MPLS domain comes,
:>how can we find out which Egress LER will route to the Destination,
:>because at Ingress point we have label to Egress LER and not the
:>Destination in the Switching Table

Hi Neetu,

If I understand the question correctly, at the Ingress LER, you'd run BGP
to map destination prefixes to Egress LER.  Hence, destination prefixes to
LSPs.
