Hello there,
I'm looking forward to set up a nice System Center 2012 R2 Environment, with one Major Site where the Infrastructure for System Center and the Virtual Machines reside. There are another 2 Sites which will get an NVGRE Gateway so I can have the same IP Setup both sites matched to the deployed VMs. We will call the Site where all the big Hardware sits Site A, Site B and C only will have a NVGRE Gateway so that physical Machines on Site B and C can Access their VM's with their locally assigned IP Addresses and not what Site A is configured with.
My question seems a bit silly but I haven't found any answer to this (neither in the Hybrid Cloud Guide nor somewhere else)
If I deploy the following layout on all 3 sites (simplified), what features will the Switch on the local site need? Any certain numbers like ARP Entries or anything?
Layout: [Hardware] ---- [Switch] ---- [NVGRE Gateway] ---- [ISP]
My ISP has assured me I'm on full IPv4/6 Dualstack and I can have an ASN on the site where the Hardware is. The other two sites are simple enough ADSL IPv4 Lines where the x86 commodity Hardware NVGRE Gateways will be set up. I understand that eBGP will not be possible with this kind of Setup but iBGP should be working?
So do I need something like a Juniper EX-4200+ Series Switch on each Site behind the NVGRE Gateway or will be a basic L2(+ ?) Switch do the Job on the local Networks or do I need to watch out for some specific Switch supported features to get going?
Thanks for your help in advance guys!
