Configuring the Router
To support IP over ATM communications on the ATM router, you need to configure the following
interfaces:
• ATM interface to switch
• Interface to the LAN that hosts the management workstation
To configure the ATM interface to the switch, you need to do the following tasks:
• Create an ATM interface
• Assign an IP address to the ATM interface
• Assign an AESA to the ATM interface
• Configure the ATM interface to be the ATMARP server for the switch
If the router IP address for the ATM interface is on the same subnet as the IP address on the switch ATM
interface, no additional configuration is required for the router IP LAN interface.
To configure the IP interface to the LAN, you need to do the following tasks:
• If the router IP address for the ATM interface is not on the same subnet as the IP address on the
switch ATM interface, you must manually configure on IP host-route for each MGX 8850 to which
the interface will connect.
• Configure a routing protocol to broadcast the switch IP addresses to the LAN or create default routes
to the switch on the management workstation.
The procedure you use to configure the ATM router will depend on the router you are using. The
following example lists commands you can use on a Cisco router to support IP over ATM
communications with the Cisco MGX 8850 and Cisco MGX 8950 switches.
