2 Routers - Back-toBack CSU/DSU - How to route & limit bandwidth?

Hi,

I am attempting to achieve the following.

1. Limit 2Mbps of bandwidth coming from the Internet

2. Route all traffic from and to the Internet through router1's FE 0/0 via SE 0/0 back-to-back via router2's SE 0/0 then through FE 0/0.

3. Use router1 to use ip forwarding to 192.10.108.145

4. Use router2 to use ip forwarding from 192.10.08.148

4. Only see FE 0/0 ip addresses on both routers because SE 0/0 on both routers will be private addresses just for the back to back.

Is this the best way to go about this?

(Internet)---> 192.168.10.146 (CISCO FE 0/0) <---> 172.60.1.1 (CISCO SE 0/0) <--> 172.60.1.2 (CISCO SE 0/0) <---> 192.10.108.147 (CISCO FE 0/0) <--> Network

Here is a sample of the configurations. I left out the password, hostnames etc.

Thanks!

Re: 2 Routers - Back-toBack CSU/DSU - How to route & limit bandw

The bandwidth subcommand sets an informational parameter only; you cannot adjust the actual bandwidth of an interface with this subcommand. Specifically, this value is what routing protocols use to determine paths, among other things.

The “clock rate” command is more what you need, especially if you are just doing a back-to- back connection.

Configure the clock rate command on your csu router. How to verify which cable is connected to your router is: show controller (interface address)

Put the clock rate on that router.
