Split PPP connection

I would like to split my 1.5mps PPP connection into two, one 1mbps, and one 512kbps. Which I would like to use the 512kpbs connection for connection to 2 specific IP addresses and the 1mpbs for the rest of the network. How can I do that? Thankyou very much.

Re: Split PPP connection

You will need to time-slot channelize your line. Consult your DSU/CSU vendor for information about how to do this. Your router will also need multiple serial interfaces, or a special channelizable interface, to do this.

Re: Split PPP connection

So I have to contact my carrier in order to do this? Cant it just be some configuration on the router itself? please let me know the commands that I will have to use in the configuration.

Re: Split PPP connection

The other responce was spot on. A channalized T-1 interface or drop and insert CSU/DSU with 2 serial lines will work.

Another way to accomplish this with the hardware you have is to use frame relay encapsulation.

Assign 2 subinterfaces, use frame relay traffic shaping on each subinterface to limit bandwidth.

In order to have frame relay work in a point to point circuit, either disable LMI on both routers or turn on Frame relay switching on one router.

Re: Split PPP connection

Hi,

The other ideas are right on, but heres another idea...

You could use the existing PPP connection and use CAR (Committed Access Rate) to rate-limit the traffic to 512k for the 2 IP addresses and rate-limit the rest to 1mbps.
