BGP and MPLS

[Aneek]

I have difficulty understanding BGP Labelled Unicast. 

Pls, explain the concept.

BGP speaker uses BGP-LU to attach the MPLS label to an advertised Interior Gateway protocol (IGP) prefix and distribute the MPLS label mapped to the prefix to its peers. The speaker may advertise more than a single route to a destination as long as such route has its own label.

Good understanding here with an example :
