My situation is as follows:
I have 3 remote sites and one main location (4 sites total). Now, starting with the main location, I have 3 separate circuits coming in there (each of which are point to point links via frame relay to each of the remote sites. i.e.. One line per remote site). Each of these physical circuits has its own serial interface on the router. And each of those 3 physical circuits in turn, has 3 pvc's on them (each as their own sub interface on each of the 3 serial interfaces). (9 pvc's total). So if you look at this from the viewpoint of having one main and one remote location, there is a physical line with 3 pvc's on it coming from one single location and terminating at another single location.
To make matters more difficult, this is the situation I have been given to work with. Getting another type of line/connection is not an option. So given this scenario, I was wondering if there is anyone that knows how to set up multilink frame relay interface(s) so as to bundle the 3 pvc's for each location. I want to do this so that I can use all 3 pvc's as one multilink interface and take full advantage of the throughput given to me for each location. The current setup is just using weighted routes for each of the pvc's, for each of the sites? Not my first choice, nor is it an acceptable solution. Ideally I would like to have 3 routes at the main (1 for each of the remote interfaces, which would be the multilink interfaces)
Any help would be greatly appreciated, and any sample configs to go with the help, would be even more greatly appreciated. FYI, I have set up a multilink interface with 2 t1's so as to combine their throughput, but never with frame relay.
Hardware for the sites is as follows: (Main - 2621) (Remotes - 1721) All are running IOS 12.3
