I know I'm showing my inexperience here, but I desperately need help. =) Installing a new 3745 router at our corporate office. I was unable to 'preconfigure' as I needed to remove WICs from existing router (3640) to add to new router so that I could configure it.
Here's the problem, copied and pasted config into new router - connected and booted it up - everything looked greatu up until I tried to bring up all of the interfaces. Frame-Relay will not come up.
I was doing research and there was a note stating that when using subinterfaces for FR, they must be configured and brought up before their serial interface is brought up. That if the serial interface was brought up before the subinterfaces, it could screw up the Inverse ARP, preventing connection?
This is our main router (internally), I have to bring down all of our branches (and automated teller machines!) to replace it - so if this is definitely not my issue, I need to do more research before attempting again.
P.S. When I put the 3640 back together and booted it, FR came right up, so I know it's me - not them. =)
Thanks in advance for the assistance!
