Chapter 24 Configuring ATM Router Module Interfaces

Configuring LECs on ATM Router Module Interfaces (Catalyst 8540 MSR)

Example

The following example shows how to configure two LECs on an ATM router module interface:

Switch# configure terminal

Switch(config)# interface atm 1/0/0.4 multipoint

Switch(config-subif)#ip address 40.0.0.1 255.0.0.0

Switch(config-subif)#lane client ethernet VLAN4

Switch(config-subif)# exit

Switch(config)# interface atm 1/0/0.5 multipoint

Switch(config-subif)#ip address 50.0.0.1 255.0.0.0

Switch(config-subif)#lane client ethernet VLAN5

Switch(config-subif)# exit

Switch(config)# router ospf 1

Switch(config-router)#network 40.0.0.0 0.255.255.255 area 0

Switch(config-router)#network 50.0.0.0 0.255.255.255 area 0

For more information on configuring LECs on ATM router module interfaces, see Chapter 13, “Configuring LAN Emulation.” For a detailed description of LANE and its components, refer to Cisco IOS Switching Services Configuration Guide: Virtual LANs.

LEC Configuration Examples

The examples in this section show how to configure LANE clients (LECs) on networks with two routers and one Catalyst 8540 MSR. For detailed information on configuring the LANE server (LES), LANE configuration server (LECS), and broadcast-and-unknown server (BUS), see Chapter 13, “Configuring LAN Emulation.”

Caution For performance reasons, avoid configuring the LANE server components on ATM switch routers. Instead, configure the LANE server components on a router such as a Cisco 7500 series router or a Catalyst 5500 router with a LANE module installed.

LANE Routing Over ATM

The following example shows how to configure LANE routing over ATM using the ATM router module. Figure 24-3shows an example of a network for LANE routing over ATM.
