  • Page 26: Basic Frame Relay Configuration

    Basic Frame Relay Configuration North American routers are configured to have frame relay enabled as the default setting. With frame relay enabled, the router will communicate over WAN connections to other frame relay units via frame relay Permanent Virtual Circuits (PVC). From 1 to 40 PVC’s may be defined to connect to other frame relay units.
  • Page 27 Configuration: The default configuration for routers shipped outside North American is to have frame relay disabled. To run frame relay on these routers, Frame Relay enable Location: Main Ä Configuration The router will request confirmation of the change, enter “yes”. For an router with a CSU-DSU interface, the default clock speed that the router will expect to receive from the DCE link is 64Kbps.

  • Page 28: Auto Learning The Frame Relay Configuration

    Applications Auto Learning the Frame Relay Configuration The router is pre-configured to query the frame relay service to auto- learn the LMI type and the PVC DLCI numbers. This auto-learn function allows the router to be plugged into the frame relay service and auto-learn the PVC configuration to become operational without further manual configuration.

  • Page 29: Manual Configuration - Lmi Type

    Manual Configuration - LMI Type The LMI Type option allows you to manually specify the type of Link Management Interface in use by the Frame Relay service provider for the Frame Relay service. When the LMI type is set to none, the router simply creates frame relay packets and sends them on the defined PVC’s.

  • Page 35: Should You Bridge Or Route

    Applications Should You Bridge or Route? When connecting two Local Area Networks together, the first question to ask is should I bridge or route? The decision to bridge or to route may be decided by how the existing networks have been already set up. Bridging should be used when the network consists of non-routable protocols or routable protocols using the same network numbers.

    Applications PPP Link Configuration Overview A PPP (Point to Point Protocol) connection between two routers may use a number of Network Control Protocols (NCP) for communication. An IP router connection will use the Internet Protocol Control Protocol (IPCP) NCP for all IP communications. An IPX router connection will use the Internet Packet Exchange Control Protocol (IPXCP) NCP for all IPX communications.

    Configure Firewall The router provides Firewall security for restricting access between any two networks connected through the router. Firewalls are set up on a per connection basis for the LAN and remote sites. The direction of filtering is from the perspective of the router; incoming traffic is from the network in question to the router, outgoing is from the router to the network.
