D-Link DI-1162M manual Multi-Link PPP Configuration

DI-1162/DI-1162M Remote Access Router

Items in the above submenu are described as follows:

♦RADIUS State – Enables or disables RADIUS.

♦Type – Refers to the type of external password protocol. Currently, only RADIUS is supported.

♦Server IP Address – This is the IP Address of your UNIX or NT-based RADIUS server.

♦Port – The port number for the RADIUS server. The standard port number specified by RFC 1700 is 1812 (shown above).

♦Key – This is a password used to identify the router as a valid RADIUS client.

Multi-Link PPP Configuration

Multi-link PPP (MLPPP) is a standard (RFC 1990 and RFC 1717) for inverse multiplexing, a method of combining individually dialed channels into a single, higher speed data stream. MLPPP is an extension of PPP that supports the ordering of data packets across multiple channels. Although MLPPP can be implemented on any WAN device, it was the rapid emergence of ISDN BRI as a cost efficient higher bandwidth alternative to modems which has driven the evolution and acceptance of MLPPP. Typically MLPPP is used to combine the speed of two ISDN BRI B-Channels to get 128Kbps of virtual capacity.

Before implementing MLPPP on the DI-1162/DI-1162M, please ensure that your ISP or the device to which you are connecting supports, and is configured for MLPPP.

MLPPP can be implemented in two ways, dynamically through the use of the Bandwidth on Demand (BOD), and statically. BOD causes the second WAN port to place a call and add bandwidth to the WAN connection when the BOD High Threshold is exceeded for the Add Bandwidth Delay period. Bandwidth can also be subtracted when WAN throughput falls below the BOD Low Threshold and Subtract Bandwidth Delay parameters. Thus, BOD economizes MLPPP by maintaining only the bandwidth needed.
