RE: Back to Back Routers [7:73897]
What kind of fiber connection is coming in on the e0 of the 1601? How are you measuring that 1.6Mbps throughput? Bandwidth command doesn't influence interface speed. Clockrate does, but you have that set to 400 in the config below. That should translate to roughly 4Mbps. It might happen though that the serial cable can't support that high speed. Do you see any errors on the serial interface? Or lot's of collisions on the Ethernet interfaces? Thanks, Zsombor Paul Carter wrote: I have a 1601 router and a 2509 to practice with.
