There are two data centers at opposite side of the coast. A spoke router near Data Center 1 has two WAN links and connect to each ABRs at Data Center 1.
For redundancy purpose, a third WAN link is installed and connected to Data Center 2.
My question is, how would you design your area so that if Data Center 1 fails, a spoke router will fail over to Data Center 2? Group all 3 links into one Area or Group 2 links to one Area and the third link to its own area?
Thanks for your help!
