Gone thro the some docs on MPLS and below are the questions arised out that.
1. when we use label switching protocol how router will assign label# for the prefix as we are not configuring any range or number when we enable label switching.
2. In enterprise MPLS IP VPN design , what protocol service provider use in their backbone is it OSPF or BGP and if it is BGP do they use LSP or BGP PIGGYBACK to carry labels.
3. how service provider backbone routers normally interconnected is it thro IPLC or ATM links for providing Enterprise IP VPN solution.
Thanks in advance
