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.
