Routing protocol Over Nexus

kyeremeh.samuel · ‎02-15-2012

I just bought 2 Nexus 7000 to upgrade my primary/Production Data Center from 6509/MSFC. I'll keep the 6509E/SUP720 for the DR Data Center.

I have ordered two 10Gig Wan Pipes between the Production and DR. In other words between the Nexus 7000 and the 6509E.

My problem is that i do not know the best way to do the routing between the 2 Data Centers. Currently I have MPLS with a provider connecting the 2 Data Centers using BGP on the CEs and I'm running eigrp in locally in the Cores.

After the 10Gig comes to life, the MPLS will go away.

My QUESTION: Should i run ibgp between the 2 Nexus and ibgp between the 2 6509E/sup 720 AND THEN run ebgp between the Nexus and the 6509/sup 720 over the 10Gig WAN? OR should i collapse everything into one eigrp domain/AS and just run Eigrp between the Nexus and 6509E/Sup 720 over the 10Gig Wan?

I have attached diagram

Please your contribution will be very much appreciated.

Thank you.

It should be fine to just run EIGRP. Why bother with BGP complexities when EIGRP would do the job and converge faster.

Also, when running BGP, you still would need to have EIGRP any ways.

Thanks.
