Starting DLSw over Frame Relay BNN
Because BNN format does not carry the destination MAC address, incoming LAN
frames must be forwarded to a specific PVC for delivery to the host. The router
uses a Frame Relay Mapping Table to get the destination MAC address. The table
has these fields:
DLCI, which represents a Frame Relay PVC
Remote MAC, which is the destination MAC address
Local MAC, which is a source MAC address
There is one Frame Relay Mapping Table for each physical Frame Relay
interface. Each entry must have a value specified for the Local MAC, Remote
MAC, or both. Incoming LLC2 packets (such as LAN packets) are checked
against the entries in this table. If a match occurs, the router forwards the frame
only to the DLCI specified. If no entry is found, then the information is not
forwarded out this interface as a BNN packet.
For more information about the Frame Relay Mapping Table, see Configuring
LLC Services.
