If I have this simple net: 3660(FR Switch)-------------------3640
I am using NM-4T on both routers. Default (HDLC) encapsulation causes both router serial interfaces to come up. I am trying inverse ARP from Caslow book but as soon as I enable FR (or even PPP) encap, line goes down. 3660 is the DCE and supplying clock. I am not sure if someone has tried NM-4T with FR? /N Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=41250&t=41250 -------------------------------------------------- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
