Exploring EVPL / NNI redundancy options

[Mark Blackford via NANOG <nanog () lists nanog org>]

Does anyone have experience implementing redundancy on their EVPL services
within the same carrier?  For instance, I have many point-to-point
scenarios using EVPL providers to connect sites to Dallas. I’m looking to
add a new pop in Atlanta this year for expansion and redundancy.

It seems possible to have a “Site A” with a current drop off NNI in Dallas
added to the new POP on Atlanta within the same carrier network for data
center redundancy, but I am not sure how practical that is in terms of cost
and implementation. Latency would vary of course, and I am assuming they
give you a different VLAN (but maybe not?).

I welcome any comments like if this is a good idea or not, what carriers I
should consider, and experience with cost.

Thanks in advance!
