How to configure cross VRF routing (route leak) in Nexus devices?

[Steve Rodrigue]

I try to configure a simple setup (2 vrf with loopback interfaces that would be see each other). I'm hitting a "wall", because I can't set an RD in my VRF context. Here a reference to an old discussion in this community about this subject.

The final goal/objective is to leak some route between a VRF and the global routing table. I mention it, because it may require special attention and/or features.

My setup:

Nexus 6001 chassis running 7.1(0).

License LAN_ENTERPRISE_SERVICES_PKG = In Use.

Feature bgp is enabled.

Do I need to enable another package/feature?

(In the feature list, I don't see anything related to MPLS).

NOTE: I'm familiar with VRF, but on ASR and other small routers environment. So, I don't need "basic explanation". I know what config I have to put in the Nexus, but I can't. :'(

Hi Steve,

Saw the old discussion which has covered most of the options.

>Do you have an option of connecting a physical cable locally on the Nexus device? Two interfaces should belongs to different VRFs as per below.

      Nexus
+----------------+
|                |
|                |
|          VRF A +-----+
|                |     |
|                |IGP  |Local
|                |     |Loop Cable
|          VRF B +-----+
|                |
|                |
|                |
+----------------+

> Run an IGP (OSPF/EIGRP etc) over this physical path and try advertising routes between two VRFs as per your requirement.

See if it helps.

I surely tough about this solution. But we don't like it, it is not "elegant" and counter-intuitive. I'm exploring PBR. I also found out the Nexus 6000 does not seems to behave like Nexus 7000 which I also have access to.
