I have one 3500 Switch and four routers (3800). I have connected all routers to switch & want to configure Frame Relay between Routers. I know how to configure FR between routers (point to multipoint). But I have no idea how to configure Switch. I have no idea how to configure DLCI on switch so that routers can be configured for the same. I am only concerned about FR Switch configuration (Hub). Please help me.
