Mark, If I'm reading your situation correctly, I think the problem comes from the back-to-back FR link. We use 2600 routers in labs to emulate FR switching between two or more FRAD routers, like this:
R1/FRAD R3/FRswch R2/FRAD Since your goal is to get R1 and R2 to communicate in a LAN environment, you can plug them into a hub or switch, using a /30 subnet for the IP addresses on the interfaces. If you prefer to use the serial interfaces, use PPP or HDLC. I realize that you don't trust PPP, but it really is easy to configure and use. Is there some reason I'm not aware of that makes you shy away from PPP? -- TT -------- Original Message -------- Subject: Let the flamin' begin....dumbass beginner question [7:43759] Date: 9 May 2002 13:18:53 -0400 From: [EMAIL PROTECTED] ("mark") Organization: GroupStudy.com Discussion Groups Newsgroups: groupstudy.cisco I originally configured and maintain several Cisco routers at work so I'm not a TOTAL dumbass when it comes to routers but I sure do feel like one about now. I have a couple of 2500's and a 2600 router with a couple of back to back cables. I'm not doing something correctly to allow the units to talk to each other using those cables. I can telnet into each router or connect via console connection and all are working. The green lights come on the serial connections when the b to b cables are plugged in but I can't for the life of me get them to talk to each other. Can't ping from one serial port on subnet A thru the b-to-b cable to the serial port on the other router on the same subnet on any of the routers. I have checked and rechecked ip info on all. I have tried frame-relay and PPP (which I would NOT trust my configuraion of but I do know frame OK - or at least I thought I did). I have RIP and EIGRP enabled on all and have them redistributing. I have tried the DCE and the DTE at each end. This is what maybe the particularly dumbass question - Do I need to set a clock rate or data rate for a frame connection using these cables? If so the commands required would be helpful. I can look at the options available. I just need to know where to start with them. If it's not a clock rate issue, have I given enough info for anyone to give me an educated guess as to what I'm doing wrong? If not, what other info can I provide? Muchas gracias.
