VPLS or Ethernet Private Line Between Main Site and Colocation Site

Hi,

We are considering VPLS or Ethernet Private line to connect our main data center to a disaster recovery colocation site.

What I can't seem to clarify in my mind is that since VPLS would make both data centers appear to be on single LAN, do I need everything on a single IP subnet?  If I don't have enough IP addresses on my current subnet, will I need to make a bigger one that will have enough IP addresses for both the main site and colocation center?

Thanks so much!

You can.  You could also make the VPLS link a layer-3 link and have each site be a different IP network.

Yes. If you operate the VPLS as a layer-2 link, then you will need an IP network with enough addresses for both sites.
