Part IV: Routing Protocols

 <  Free Open Study  >  

Special Components Needed for ATM Lab Studies

I recommend the following equipment for your ATM exercises:

  • One LightSteam 1010 (LS1010) ATM switch

  • Two or three routers with ATM interfaces

If you have problems accessing LS1010, you can attend Cisco's "Campus ATM Solutions" class before going to a lab. The class has several LS1010s with routers, providing you with the necessary gear. Also, the Cisco ATM Solutions book provides many configuration examples/labs to enhance your comfort level with ATM.

This chapter focuses on the routers' configurations. Typically, the LS1010 does not require any special configuration unless you have a network of LS1010s. Cisco ATM Solutions provides elaborate examples and explanations on LS1010 configuration, if you ever have a need to configure one.

The routers can include a 4 XXX, 7 XXX, or 36 XX series model. Cisco has a rich assortment of product lines that include routers and switches with ATM interfaces. Table 8-2 illustrates this variety. It is important to note the assortment of ATM adaptation layers (AALs), User-Network Interface (UNI) types, and ATM service categories that are supported.

[1] Table 8-2 information is based on Cisco's product catalog as of August 2001.

[2] A member of the Catalyst 8500 family, the Catalyst 8540MSR, can also be an ATM switch. It can accept not only new modules, but also existing LightStream 1010 modules.

Cisco has various ATM router interfaces supported on multiple platforms, as illustrated in Table 8-3.
