Configuring Multiprotocol Encapsulation over ATM

Router 2 Ethernet Interface

Router2# configure terminal

Router2(config)# interface ethernet 9/0/0

Router2(config-if)# bridge-group 1

Router2(config-if)# end

Router2#

Router 2 Bridge Interface

Router2# configure terminal

Router2(config)# interface BVI1

Router2(config-if)#ip address 130.2.3.4 255.255.255.0

Router2(config-if)# exit

Router2(config)# bridge 1 protocol ieee

Router2(config)# bridge 1 route ip

Router2(config)# bridge irb

Router2(config)# end

Router2#

For more information on configuring bridging, refer to the Layer 3 Software Configuration Guide.

Confirming the LEC Configuration

To confirm the LEC configuration on the ATM switch router, use the following EXEC commands:

Command	Purpose
show lane [interface atm	Displays the global and per-virtual channel
card/subcard/port[.subinterface#]	connection LANE information for all the LANE
name elan-name] [brief]	components and emulated LANs configured on
	an interface or any of its subinterfaces.
show lane client [interface atm	Displays the global and per-VCC LANE
card/subcard/port[.subinterface#]	information for all LANE clients configured on
name elan-name] [brief]	any subinterface or emulated LAN.
show lane config [interface atm	Displays the global and per-VCC LANE
card/subcard/port[.subinterface#]]	information for the configuration server
	configured on any interface.

Configuring Multiprotocol Encapsulation over ATM

This section describes how to configure multiprotocol encapsulation over ATM, as defined in RFC 1483, on the ATM router module.

The primary use of multiprotocol encapsulation over ATM, also know as RFC 1483, is carrying multiple Layer 3 and bridged frames over ATM. RFC 1483 traffic is routed through an ATM router module interface using static map lists. Static map lists provide an alternative to using the ATM Address Resolution Protocol (ARP) and ATM Inverse ARP (InARP) mechanisms. For more information on static map lists, see Chapter 12, “Configuring IP over ATM.”

For a detailed description of multiprotocol encapsulation over ATM, refer to the Guide to ATM Technology.
