Hi Oli,
thanks again for your help,

>So if there is no other VRF on PE#2 with "route-target import 1:222" or "..

-> by disabling "no bgp default route-target filter" the result shown is PE#1
and PE#2 will directly install the route for each VRF match RD value not by
matching the route-target, because it ignore any route-target configured.
please look for "Output#1" which is the same at PE#1 and PE#2. in this scenario
I also tried using import map which is no impact. i just importing based on
same RD regarding route-target.

achieve this policy.
-> Yes, we are planning too, but at the moment I am dealing with such a mess :(
we are having a lot of PEs with multiple route-target, if cisco device is
importing routes based on single route-target then, there will be mess within
routes received in Cisco device
I also thinking about another workaround in case Cisco device unable to match
multiple route-target by filtering received route within vrf based on
prefix-list <but I haven't tried this>

! "no bgp default route-target filter
