Hi ..
I have tre different VRFs VRF-A, VRF-B and VRF-C, VRF-C is my management VRF, I need to attach a export map on VRF-A and VRF-B, so I can control witch networks will be leaked over in my management VRF-C ..
My Setup I build on 4 PE's, connected together link this
|---PE1--------PE2---|
| |
|---PE3--------PE4---|
VRF-A is connect to PE1 and PE2
VRF-B is connect to PE2 and PE3
VRF-C is connect to PE3 and PE4
ip vrf VRF-A
rd 1:1
route-target export 1:1
route-target import 1:1
route-target import 1:3 -- Add to see management ip addresses from VRF-C
ip vrf VRF-B
rd 1:2
route-target export 1:2
route-target import 1:2
route-target import 1:3 -- Add to see management ip addresses from VRF-C
ip vrf VRF-C
rd 1:3
route-target export 1:3
route-target import 1:3
If I add route-target import 1:1/route-target import 1:2, I'll se the routes, but becurse of overlapping ip adresses in each VRF, I only want to se part of the annonced networks.
In VRF-C I need to filter out routes fra VRF-A and VRF-B, so I only see the routes that I want, ant not the hole routing tabel from the VRF's,
I can't find any solution, Import map "route-map" will not solve my problem, I have tried that ..
Any ider ??,
./-Peter

Can you tell me why import and/or export map cannot help you here.
Thanks,

Export map works particular,
If the export map I attach to the VRF on PE1 I kan only see direct connecet interface's and not route's annonunced into the VRF for a CE route..
Route Show in VRF-B
10.0.0.0/8 is variably subnetted, 5 subnets, 4 masks
B 10.9.133.128/25 [200/0] via 10.50.59.9, 00:06:46
B 10.9.133.36/30 [200/0] via 10.50.59.8, 00:06:46
B 10.9.133.32/30 [200/0] via 10.50.59.9, 00:06:46
B 10.9.133.40/29 [200/0] via 10.50.59.9, 00:06:46
C 10.9.133.49/32 is directly connected, Loopback10
Routes show in Management VRF.
10.0.0.0/30 is subnetted, 1 subnets
B 10.9.133.49 is directly connected, 00:00:27, Loopback10
Access-list / Route map
route-map VRF-B permit 10
match ip address 16
set extcommunity rt 1:3 additive
!
access-list 16 permit 10.9.133.49
access-list 16 permit 10.9.133.128 0.0.0.127
access-list 16 permit 10.9.133.32 0.0.0.3
