Coneecting routers back to back

[penrose]

I need to connect two routers back to . This is fine but I want to set the bandwidth between the router to 256k. Is this possible?

Sure.. there are a few different ways to do this. You can use the serial ports and a pair of CSU/DSUs with a T1 back to back cable, T1-WICs with built in DSU/CSU and same cable, HSSI back to back if you have money to burn ;-). I have not tried the "normal" back to back cables at anything faster then 64K.. I'm told it fails but I suspect there are a few variables there.. quality of cable, length and so on. It might work with one of the 3 foot cables instead of the normal 10 footers.

Why not use a DTE cable connected to a DCE cable and run one with clocking and the other without. Set the speeed of one of them to bandwidth 2000000 (anyone got the actual syntax?) and you can do this up to 4Mbit/s theoretical max on X.21 interface cables. RS232 and V.35 cables are limited in theory but in practice will run 2Mbit or higher without issues depending on your routers, connectors and protocols.

The actual syntax is "clock rate 6000000" on the DTE interface. I've had 3640s running at 6Mbit/s back-to-back V.35 (10 foot cables)no problem. If you use compression, you can squeeze a bit more out of the connection. The practical V.35 limit is 8Mbit/s according to Cisco's documentation, but my routers wouldn't accept anything higher than 6000000 with the clock rate command.
