why BGP used in MPLS

Hi there

First of all mpls can work with any routing protocol including ospf

Mpls uses lable switching that built based on the local router routing table

Please see the below link to understand how mpls works

https://learningnetwork.cisco.com/docs/DOC-5914

However with mpls networks an extintion of bgp used to support virtulization using what is called MP-bgp

That can run L3vpn between edge routers called PE to exchange routing over the core mpls network

Hope this help
