Frame Relay Configuration Task List - D-Link DI-1750 Reference Manual

5.1.5 SLIP
The point-to-point data link layer protocol(such as SLIP, PPP) is needed for either the router-router
leased line connection, or dialup host-router connection, to complete encapsulation of frame, error
control, etc.
SLIP is a data packet protocol, which defines series of characters to encapsulate the IP packet on serial
line. For point-to-point line, use TCP/IP.
SLIP implementation follow RFC 1055 and supports RFC 1144 suggested TCP/IP header compression.
It is also supports various connections of network equipments and hosts through SLIP.
5.1.6 PPP
PPP provides the transmission of multiprotocol datagram on point-to-point link. D-Link Router mainly
implemented following functions:
♦ Follow RFC1661 and support Link Control Protocol to build, configure and test the link of data.
♦ Follow RFC1662 and support the encapsulation of IP and other upper protocols on PPP that
implementthe IPCP of Network Control Protocol (NCP).
♦ Follow RFC1334 and support two universal authenticating protocols that include PAP and CHAP.
♦ Follow RFC1144 and support header compression of TCP/IP to improve the available data
throughout.
♦ Provide widely option control that adapts the situation in much more as possible and supports
various connections of network equipment and host through the PPP protocol.
♦ Support synchronous and asynchronous PPP protocol.
♦ Support the option of multi-link to implement multi-link binding.
♦ Support callback that provides higher security.
♦ D-Link Router supports RADIUS protocol while use as dial-up server for authentication,
authorization and accouting of user's indentity. Userinfo is saved in a host. The host and Router
exchange the messages through RADIUS protocol.

5.2 Frame Relay Configuration Task List

5.2.1 Configuring Frame Relay
This chapter describes how to configuring Frame Relay on the router. For a complete description of the
commands mentioned in this chapter, refer to the "Frame Relay Commands" chapter in the Router
Products Command Reference publication.
5.2.2 Frame Relay Hardware Configurations
One of the following hardware configurations is possible for Frame Relay connections:
Routers can connect directly to the Frame Relay switch.
Routers can connect directly to a Channel Service Unit/Digital Service Unit (CSU/DSU) first, and the
CSU/DSU connects to a remote Frame Relay switch.
Note:
Router can connect to a Frame Relay switch through a direct connection and others through connections via CSU/DSUs.
However, a single router interface configured for Frame Relay can be only one or the other.
The CSU/DSU converts V.35 or RS-449 signals to the properly coded E1/T1 transmission signal.
Figure 1 illustrates the connections between the different components.
