ROUTING IP

This chapter shows how to configure units to route IP data packets between two networks, using ISDN.

Configuration steps are given for:

■Manual configuration of the central site router.

■Quick Configuration of the remote router.

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

Routing IP

If data is required to be shared or transferred between IP networks with different network numbers or subnets, the IP protocol cannot be bridged and has to be routed.

Configuration Options

When configuring a unit to route 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, 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.

Alternatively, the remote site unit can be configured by utilizing the remote configuration facility (REM) of the central site unit.
