Hi Oli, thanks again for your help,
>This could be caused by BGP's automatic RT filter, which is not examining the >import route-maps when deciding whether or not to accept a vpnv4 iBGP update. >So if there is no other VRF on PE#2 with "route-target import 1:222" or ".. >1:333", you need to enable -> 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. >You still want to consider re-designing this, using distinct RTs to 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> ! #Output#1 !
