Frame Relay Issues, plus some misc. questions.

First, let me say thanks to anyone who is going to help.

Alright, to the nitty-gritty, I have two 56k routers w/56 CSU/DSU cards in them connected back to back with a rollover cable. I don't believe the rollover plays a roll in this problem, becuase I have CD lights on both the routers.

I am new to dealing with routers, but the goal I'm trying to achieve is to link two stores with frame. I believe most of my configuration is correct, but I cannot get the line protocols to come up on the frame. Below should be most or all of the information you need. One last thing -- as I said, I'm new so if you guys see something that may not necessarily be applicable to my problem, I'd appreciate it if you brought it to my attention.

What is causing these annoying errors and how can I fix them?

%Error opening tftp:// (Timed out)

%Error opening tftp:// (Timed out)

%Error opening tftp:// (Timed out)

Also, the address I supply to the Frame sub interface is just for connection between the two routers, correct? And the same thing for the DLCI, I don't understand why I need another IP address for that.

The routing I'm trying to set up is just one network address. Can both stores be on the same network address? Or do I need something like this: Store 1 -, Store 2 -

Well thanks again for the help, I know it's alot of questions, I just hope someone can help me some =)

Re: Frame Relay Issues, plus some misc. questions.

First: "no service config" will stop the errors.

2nd: I think you'll have a tough time with frame-relay back to back over 56K internal CSU/DSUs. The key is to enable "frame-relay switching" in global config on the router that is supplying clocking, and then "frame-relay intf-type dce" on the main serial interface (not the sub-if).

The problem is, I don't know if a WIC 56K CSU/DSU will accept that last command, but give it a shot.

3rd: You'll have to set up both stores on seperate IP addresses unless you plan on bridging rather than routing. I suggest stronly that you route.

The IP addresses for the sub-ifs can be "ip unnumbered ethernet0" to save IP space.

What he said and, Frame switching requires at least a plus level IOS.
