I have a question about Frame Relay routers. Watching Rene’s video about recommended CCNA equipment, i am thinking about adding a fourth router into my setup.
I currently have 3 Cisco 1841 routers which are serial linked via WIC-2T connections.
I am a bit confused to which router to go for as I would like to try at doing Frame Relay, from what I understand I would need 3 serial connections from the frame relay router, could this work if I had another 1841 router using 2x 2 port WIC-2T modules then connecting them using the Serial0/1 interfaces ? Or would I have to invest in something like a Cisco 2801 Router which will allow me up to 4 modules to be installed with 3 individual WIC-2T modules ?
I include a pic of my setup for reference if needed
