  • L2 versus L3 on your WAN

    We are running Comcast Fiber between sites.  I was wondering what the best practice is for using Layer 2 or Layer 3 across the link.  We current use both.  Are there security reasons for doing one versus the other?  Also interested in hearing general thoughts on it.
