I am working on a project for data center migration. I would like to know the design solutions and their comparisons for DCI.
For example L2 extension over L3 or over IP.
Which solution is best for datacenter interconnect. Retaining the L2 domains at each data center or using IP?
Can anybody guide me to the link or PDF which talks about the pro's and con's of each solution?
Thanks in adbvance,
