Connect the Frame Relay line with the Eicon Interface Card (1)

It is believed that many technical personnel are looking for a way out for the frame relay network established using the Eicon wan interface card a few years ago:

The computer with the Eicon Multi-Protocol Smart Wan ISA interface card c21 has been out of service for a long time and cannot be replaced by a new machine with an ISA slot. The Frame Relay connected to the Eicon WAN Interface Card is generally connected to only one computer, unable to achieve the purpose of LAN interconnection ......

DENT: 2em "> As mentioned above, this article provides a case of" using a Cisco router to connect to a frame relay line and backing up an Eicon WAN Interface Card.

1. First, obtain the technical parameters of the frame relay line:

For vro configuration, the required parameter is

1) Local dlciData Link Connection Identifier data Link identification code for Frame Relay) --- each frame relay virtual circuit identifies itself with DLCI), which can be obtained from the running "Eicon Administrator/Configurator" software: see Frame Relay dlci.

, Frame Relay dlci

2) IP address of end A, which can be obtained from ipsettings of the eicom card.

2. Upgrade the IOS of the Cisco 1603 router:

Use a Cisco router instead of the Eicon WAN Interface Card to connect to the frame relay line

The network transformation scheme in Figure "using A Cisco router instead of the Eicon WAN Interface Card to connect to the frame relay line" shows that the router is required to connect the network of A to B. In order not to affect the network structure and configuration of the B-end and its applications, the-end router must adopt the NAT mode.
