Configuring ATM Router Module Interfaces
Configuring LECs on ATM Router Module Interfaces (Catalyst 8540 MSR)
To configure a LEC on an ATM router module interface, use the following commands, beginning in
global configuration mode:
global configuration mode:
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

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
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
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.

Step 1
Switch(config)# interface atm

Switch(config-subif)#
Creates the ATM router module

Note
The ATM router module only supports
point-to-multipoint subinterfaces.

Step 2
Switch(config-subif)# ip address ip-address mask Provides a protocol address and subnet mask for
the client on this subinterface.
Step 3
Switch(config-subif)# lane client ethernet
elan-name
