We are in the process of moving to Verizon EVPL for a connection to a remote site. Verizon is offering EVPL for this connection. According to Verizon, most people use a router as the endpoint for the EVPL, but if this is a layer 2 connection, I should be able to use a switch also correct?

Is there an easy step by step procedure somewhere on how to set up multicasting on a LAN, for say ghosting 10 workstations? And what if I needed to multicast from a server in on site across an MPLS network to the 10 workstations? How would i set that up?

We have a Cisco Telephone system with Cisco phones. I have limited knowledge of how this system works in a general way. I have some questions that maybe someone can help me to understand: 1. In a business telephone system, is the PRI that is used the same as an ISDN PRI? 2. If so, is it...
