BPG VPLS route reflect doesn't work

Hi:

I got this scenario with three RB450 A <–>B <–>C in a BGP_VPLS scenario. Each one have a customer1 in a VPLS design. A is a Peer of B and C the same with B. I activate de route reflect in the B router and when I check the print status on bgp peer the status stay in IDLE. When I turn it off, it get established again. The thing is A don’t get peered to C and don’t pass any data from A(customer1) to C(customer1) without create a direct VPLS from A to C.

Thanks for any hints…
