I will be activating a MPLS circuit mainly for voice traffic on our new IP phone system. &nbsp;The question I have though pertains more to the network infrastructure and specifically if I will be creating a conflict or problem. &nbsp;Here is what we currently have in our two sites:<br />
<br />
Michigan Site: ABC.Local<br />
Server 2008 R2 Primary DC (holds all roles) with Exchange 2010 installed<br />
10.1.1.0 255.255.255.0 (Data Vlan 200 on switches)<br />
172.16.10.0 255.255.255.0 (Voice Vlan 100 on switches)<br />
Washington Site: XYZ.Local<br />
SBS 2008 <br />
192.168.16.0 255.255.255.0 (Data Vlan 200 on switches)<br />
172.16.11.0 255.255.255.0 (Voice Vlan 100 on switches)<br />
<br />
The MPLS circuit has managed routers and will be routing both the data and voice vlan. &nbsp;I understand that SBS is supposed to be the only Primary DC (holding all roles) in a network, by activating a MPLS circuit with the Data vlan routing between subnets will I create a conflict and throw the SBS into an hourly reboot until I remove the Data vlan or should I be ok?

MPLS (IPVPN) Will it cause problems

A router is a networking device that forwards data packets between computer networks. Routers perform the "traffic directing" functions on the Internet. The most familiar type of routers are home and small office cable or DSL routers that simply pass data, such as web pages, email, IM, and videos between computers and the Internet. More sophisticated routers, such as enterprise routers, connect large business or ISP networks up to the powerful core routers that forward data at high speed along the optical fiber lines of the Internet backbone. Though routers are typically dedicated hardware devices, use of software-based routers has grown increasingly common.

Small Business Server (SBS) is a line of server operating systems targeted at small businesses by bundling the operating system with a number of other Microsoft products that would normally need to be purchased or licensed separately. The most notable inclusions are Exchange, SQL Server, SharePoint and ISA/TMG (Microsoft's firewall and proxy server).

Networking is the process of connecting computing devices, peripherals and terminals together through a system that uses wiring, cabling or radio waves that enable their users to communicate, share information and interact over distances. Often associated are issues regarding operating systems, hardware and equipment, cloud and virtual networking, protocols, architecture, storage and management.
