Your issue probably has to do with multiple iBGP paths in the RR. It
will only install (advertise) one of them and then one or the other of
your PE's will get that route. This PE (PE2 in your case) will show
the distant route and local CE originated route.
You can monitor your RR with a show ip bgp vpnv4 all after a clearing
of the bgp neighbors. You should see the prefix coming from both PE's
but then one will disappear when it gets installed in the RIB.
