can i create "Simple" frame relay cloud using this ..if not how many routers are needed for this ....thought of doing ospf in frame relay cloud ...Help pls
a good link is the following to FR switching config examples
When connecting routers back to back with serial interfaces you need :
to provide clock with clockrate on the interface were the DCE V.35 cable is connected (V.35 female to check cable use sh controller serial x/y but not supported on all platforms)
to define one side as the FR DCE that will behave as the FR switch (that here is not present).
Frame-relay DCE is defined on the router that performs frame-rel switching
Topology is simple : have every router connected with a serial interface to a serial interface of the router acting as FR switch
using the notes above.
Use on DTE routers point-to-point and point-to-multipoint subifs according to your needs to deploy different topologies.
Hope to help
