My company have subscribe a VPN MPLS to interconnect two sites. The ISP I have choose install one router on each side and set QoS on this link (70% VoIP, 20% Data and 10% access). On each side I have a DSL link for classic Internet access. I'm a newbie in VPN so I have some questions to integrate this link in my network.
1. I suppose this link is like an L2 and transport VLAN on each side ?
2. Is this possible/a good practice to centralize service like DHCP/DNS/AD on the central site ? I use Microsoft DHCP.
3. What is the settings I need to use for the VoIP part ?
If you have conf or example to help me, thanks.
