A Complete LANE Network

Figure 9-26 pulls together many of the concepts and commands discussed earlier in previous sections. This section also shows the configuration for an ATM-attached router.

Figure 9-26. A Complete LANE Network

The network consists of two Catalysts that contain Ethernet and LANE modules. Each Catalyst has been configured with two VLANs that use ATM as a trunk media. VLAN 1 is transparently bridged to ELAN1, creating a single broadcast domain. VLAN 2 uses ELAN2. Both Catalysts have two LANE Clients, one for each ELAN. Cat-A is acting as the LES/BUS for ELAN1, and Cat-B is serving as the LES/BUS for ELAN2. Example 9-10 shows the configuration code for Cat-A.

Example 9-10 Cat-A Configuration for the LANE Network in Figure 9-26

Example 9-11 shows the configuration code for Cat-B.

An ATM-attached router on a stick has also been configured to provide routing services between the VLANs/ELANs. To function in this capacity, the router must be configured with the two overhead PVCs on the major interface and two subinterfaces containing LANE Clients and IP addresses. The router is also acting as the LECS for the network. Example 9-12 shows the configuration code for the router.
