Nexus 7K inter-VRF solution

[davidcheung]

Hi all,

We are try to find a solution to send traffic from one VRF to another VRF on the same 7K chassis vDC not through external box, like switch/router/firewall layer 3 box.

any recommendation is highly appreciated.

hy

you have to configure redistribution via MBGP - There's a nice howto on Jeremy's Stretch Packet-Life blog:

Hi Marcel,

Thank you very much!

However,

"Cisco NX-OS prevents route leakage (import or export) between VRFs. "

In addition, we don't want to introduce any new box.

huuuff, didn't know that! Sorry!

Not sure if this is a change in the past four years, but "Cisco NX-OS supports route leaking (import or export) between VRFs, both in VRF lite and MPLS VPN scenarios. For more information on route leaking, see the Cisco Nexus 7000 Series NX-OS MPLS Configuration Guide."
This is from the Nexus 7000 VRF config guide

Here is a link to the MPLS Config guide that it references

This on top of the Link that Marcel posted, helped me to get this figured out for my environment. I saw this post during my search for an answer and so once I wanted to share my further findings.
