Hi Chuck, I have sent countless messages to the group. None seem were posted!!!! Would you post the following for me this is kind of urgent. (Is there a filter somewhere for people who ask dum or too many question??) Thanks, Pierre I have spent many hours trying to comprehend the exerpt bellow (from Cisco CD). Still no light. Can someone help? "This command is typically used for subinterfaces; however, it can also be used on main interfaces. Using the frame-relay interface-dlci command on main interfaces will enable the use of routing protocols on interfaces that use Inverse ARP. The frame-relay interface-dlci command on a main interface is also valuable for assigning a specific class to a single PVC where special characteristics are desired." 1. How can the command frame-relay interface-dlci enable the use of routing protocols??!!?? 2. What do they mean by "specific class"? 3. What characteristics are they talking about? Please explain AND illustrate each point... Thankfully, Pierre-Alex _________________________________ FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
