BRIDGING AND IP

This chapter shows how to configure units to operate as bridges, using the Internet Protocol (IP) data packets between two networks for management and control only.

Configuration steps are given for:

■Manual configuration of the central site unit.

■Quick Configuration of the remote unit.

■Remote configuration of the remote unit from the central site.

Bridging and IP

It is essential to remember that a bridged network using IP for management only, even if it consists of several segments, always has the same IP network address for each segment. If any segment of the network has a different IP network address, then data must be routed to and from that network segment.

Configuration Options

When configuring a unit to bridge IP packets using a dial-up ISDN link between a central site and one or more remote sites, it is recommended that the central site should be configured manually first.

The central site unit cannot be automatically configured using the Quick Configuration facility of the unit because this facility requires a ready-configured unit to act as a reference point.

The Quick Configuration facility should only be used at a remote site.
