Network Lab

Answered Question

I need some help with our network Lab.

I'm working on my CCNA and I have a 1720 router with two 56K/Wic dsu cards and would like to know what's needed to connect both cards to simulate a frame relay connection using this router.

should I make a cable to make the connection between the cards, and what's needed to get both talking and the protocol working.

thanks for any help you can give on this.

You need separate routers for each frame relay endpoint, and one for a frame relay switch. You can't route packets externally between 2 interfaces on the same router.

I have done this with serial interfaces between the routers, but never with WIC internal CSU/DSUs. It should work, but I couldn't find any examples of this.
