Chapter 8: Magnum Router Specialized Functions
This chapter covers the specialized functions of the Magnum Router. These functions include
Virtual Routing of DLCI’s, MVoIP (Micro-Band Voice Over IP) and Hybrid RIP routing.
In the case of Virtual Routing and MVoIP, these are proprietary functions and a Magnum Router
is required to be at each end-point of a circuit. Hybrid RIP is a special configuration issue that
can operate with other brand-x routers, but it’s programming is different than programming a
normal RIP routing system.
Virtual Routing
The Magnum Router allows for frame-relay connections in several different ways.
One way is by using a directly connected DLCI. This would be a connection where the input
DLCI and output DLCI are the same number.
Direct Connect DLCI’s
Networks with only one connection at each end point are also known as direct connect. These
PVC’s do not need to use virtual routing as all data is running on one DLCI. Thus, the supplied
public DLCI would also be the private DLCI.
For example:
If the only traffic that is to be passed through the Magnum Router is IP, then a directly
connected DLCI would work. This means that the public DLCI of the Input Port is passed
directly to the private DLCI of the Output Port using the same DLCI number for both ports.
In this example, the public DLCI of 100 is passed directly to the E1 port as DLCI 100.
Virtual DLCI’s
The definition of a Virtual DLCI is that it is a single PUBLIC DLCI that is multiplexed into several
PRIVATE DLCI’s.
If the Frame Relay provider has supplied a circuit with only one DLCI, and multiple connections
are required (one for a Marathon and another for Ethernet), then Virtual Routing would be the
solution.
