Hi Top,
would it be an option to filter your own nets (9.9.9.9 and 99.99.99.99) out
of the BGP updates coming in from the MPLS cloud. You could then do a soft
reset on your BGP neighbor so the peering will stay up but your networks
should then "disappear" from the BGP updates coming in to you. Probably best
to do this on both R1 and R2
I hope i'm understanding your problem OK
..Pete
