Hello,
i am having problems with inter vrf routing through my network. i have two vrf's named central and cust1 and i like to enable bi directional routing between both vrfs.
i configured the vrfs on side a
ip vrf CENTRAL
rd 200:1
route-target export 200:1
route-target import 200:1
route-target import 200:2
!
ip vrf Cust1
rd 200:2
route-target export 200:2
route-target import 200:2
route-target import 200:1
in the routing table of vrf central in side a i see the routes from the vrf cust on side b.
Routing Table: CENTRAL Side a
Gateway of last resort is not set
10.0.0.0/24 is subnetted, 6 subnets
O IA 10.0.128.0 [110/11] via 172.16.128.11, 02:16:28, FastEthernet0/1.200
B 10.0.129.0 [200/11] via 150.1.5.5, 02:16:28
B 10.0.130.0 [200/0] via 150.1.7.7, 02:16:28
B 10.0.201.0
[20/11] via 172.17.128.11 (Cust1), 01:08:03, FastEthernet0/1.201
Routing Table: Cust1 Side a
Gateway of last resort is not set
10.0.0.0/24 is subnetted, 6 subnets
B 10.0.128.0
[20/11] via 172.16.128.11 (CENTRAL), 00:40:04, FastEthernet0/1.200
i checked the bgp table of the router at side a, and it looks good.
Rack1R4#show bgp vpnv4 unicast rd 200:1
BGP table version is 265, local router ID is 150.1.4.4
Status codes: s suppressed, d damped, h history, * valid, > best, i - internal,
r RIB-failure, S Stale, m multipath, b backup-path, x best-external, f RT-Filter
Origin codes: i - IGP, e - EGP, ? - incomplete
Network Next Hop Metric LocPrf Weight Path
Route Distinguisher: 200:1 (default for vrf CENTRAL)
*> 10.0.128.0/24 172.16.128.11 11 32768 ?
*>i10.0.129.0/24 150.1.5.5 11 100 0 ?
*>i10.0.130.0/24 150.1.7.7 0 100 0 ?

*>i10.0.203.0/24 150.1.7.7 0 100 0 ?
but on the route reflector which is also at side a i don't have the route as well as on side b.
Rack1R1#show bgp vpnv4 unicast rd 200:1
BGP table version is 128, local router ID is 150.1.1.1

*>i10.0.130.0/24 150.1.7.7 0 100 0 ?
any ideas how i get my router r4 to send the updates to the other side?
thanks in advanced

Hello Alex,
configuration of routers would be helpful. Is topology same as in your previous post?

Hi Blau Grana,
yes it is the same topology, R5 is my site B, R4 is site A and R1 is the route reflector. It's working now, i had to to import the route target on both sites. I thought it would be sufficiant to import it on the site a and send it through the route reflector out the the other sites.
R4
ip vrf CENTRAL
rd 200:1
export map VPN_CENTRAL_EXPORT
route-target export 200:1
route-target import 200:1
route-target import 200:2
route-target import 200:3
ip vrf Cust1
rd 200:2
route-target export 200:2
route-target import 200:2
route-target import 200:50
R5
ip vrf CENTRAL
rd 200:1
export map VPN_CENTRAL_EXPORT
route-target export 200:1
route-target import 200:1
route-target import 200:2
ip vrf Cust1
rd 200:2
route-target export 200:2
route-target import 200:2
route-target import 200:50
