MBE Family Installation and Operation Manual

 

 

MBE10-8Dis a dual WAN-port router/bridge, As a bridge, it allows connection of two remote Ethernet LANs, each consisting of up to 80 workstations to a central Ethernet LAN. As a router, it allows connection of a remote Ethernet LAN.

The MBE serial link interface options are: V.35, V.24/RS-232, V.36/RS-422, X.21, RS-530, 4W, ISDN and CSU/DSU.

Applications

MBE can be used in a wide range of applications, employing diverse communication links and LAN equipment. For more details on typical MBE applications, see the LAN RANger Series Configuration Guide.

Features

Routing and Bridging Support

The MBE Family supports remote access routing and bridging for connecting remote PCs or LANs to a central LAN over a wide variety of WAN interfaces and services. This includes ISDN, Frame Relay, Leased Line, dial-up modems, and DDS.

Routing and bridging are performed on a link-by-link basis. There are no bridging or routing limitations on the central LAN. However, additional bridges should not be connected to the remote LAN.

Router links can operate opposite any PPP standard compliant device, including third party routers and software-based PPP dialers, such as Windows 95.

Bridge links are transparent to Layer 3 protocols, such as NetBIOS and

DECNET.

A backup link may be defined, which will be automatically activated if a failure occurs on the main link.

Management

Setup and configuration can be carried out from an ASCII terminal or PC terminal emulator connected to the control port, from any SNMP management station, such as RADview, or through TELNET (see the LAN RANger Series Configuration Guide).

IP/IPX Support

Internet Protocol (IP) specifies support or MTU (Maximum Transmission Unit) fragmentation and reassembly of packets to form datagrams. The MTU defines the limit on fragment size transmitted on a physical network. The local terminal must support the reassembly of IP packets in order to read the IP datagram.

MBE supports networks that have multiple IP nets on the LAN.
