Configuration: The default configuration for routers shipped outside North America is to have frame relay disabled. To run frame relay on these routers, it must first be enabled. Selecting the Frame Relay option will toggle the setting from disabled to enabled.

The router will request confirmation of the change, enter “yes”.

For a router with a CSU-DSU interface, the default clock speed that the router will expect to receive from the DCE link is 64Kbps. If the DCE link is 56 Kbps, then the Link Speed value must be reset to 56 here.

Auto Learning the Frame Relay Configuration

The router are 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. router auto-learning conforms to RFC1490.

Manual configuration is also allowed by modifying the options within each Remote Site Profile and the individual link configuration menus.

When the router first starts up it will query the frame relay service to try to determine the LMI type on each of the frame relay links. Once the LMI type is determined, the PVC configurations will be known from the full status enquiry messages. If the DLCI numbers of the PVC’s on your service are determined during this learning process, the router will automatically create a remote site profile for each PVC. The automatically created remote site profiles will be named “LinkxDLCIyyy” where x is the physical link number the PVC is on and yyy is the DLCI of the PVC.
