DESIGN WAN Multihoming Data Centers redundancy

Unanswered Question

I am beginning a project upgrading my current Data Centers WAN links

Each DC will have seperate ISP's and I will Multihome the WAN via BGP.

 

Behind each WAN router will be a DMZ that will act as L2

Behind each DMZ router will be dual ASA that will route.

We will run EIGRP from ASA back to Data Center Nexus 7K.

 

I want to make sure that Local traffic frim each DC considers it's own WAN link as Primary.

Can HSRP between the (2) ASR's accomplish this?

I want to make sure the DC's will provide redundancy for eachother. See attached diagram for topology.

 

NO Load balancing

I want to keep the config as simple as can be, so I thought of using floating static in ASA pointing to other DC WAN link.

 

Please review and advise on most reliable configuration scenarios to accomplish this goal.

I have to admit, I am disappointed this has not generated ANY interest.

 

If someone happens to look, please advise and also consider mHSRP options for Data Center ASR's
