I want to share with you some little small hint for this MPLS topology
ip vrf asd
rd 1:100
route-target export 1:100
route-target import 1:100

without "transparent" word when we try to redistribute rip over bgp , advertised prefixes are not adverties properly.
Cisco says:
Make sure that a metric, whether a specific metric or the keyword transparent, is configured when redistributing MP-BGP routes into RIP. If one is not specified, the routes may not be redistributed.
