Importing routes on fusion router

[techno.it]

Hi Folks

I have this design implemented for a client;

FB1- F1 (eBGP)

FB2-F2 (eBGP)

FB1-FB2 (iBGP)

I have imported some enterprise routes ( data center routes) into corporate VN, however, Fusion must also have reachability to those Corporate network VN from GRT for return traffic. What is best way to accomplish, is it to import routes under VRF or create static routes on fusion ?

Any suggestions ?

Any ideas?

Does your client have VRFs in their existing networks to hand-off to or is everything going to be funneled into one routing table?  Do they plan on adding VRFs to the existing network?

There are a couple of ways to handle this depending on what the plan is for the rest of the network. 

You can:

• Not use any VRFs on the Fusion router and just bring everything into the GRT.
• Put everything into VRFs on the Fusion router (including the "GRT" routes), and use import/export between the VRFs.  Then you can hand-off to a GRT upstream.

I hope that makes sense - Let me know if you have any questions!

There are VNs that currently has L3 handofff to fusion.

Let me give an example to better explain this case

I have Prod VRF in fabric, and  L3 handoff with fusion to exit the border. I have exported the default from GRT to VRF on the Fusion router and that default route has been learned by VRF in the overlay.

The question is on fusion there should be a route in its GRT to send the return traffic to Prod VRF. What is the best way to accomplish it ?
