1721 3 router redundancy setup

Hi all,

For my CCNA R/S lab setup I have 3 Cisco 1721 routers and I would like some insight as to the best way to connect these routers together for redundancy.

All routers have 1 T1 Serial WAN WIC module installed. So does all routers need 2 of these WICs, or am I lokking at this wrong?

I am in the process of ordering the WICs and need to know before I start studying hard next week.

Also, do I use the same DCE/DTE DB60 serial cables for this setup as well, from what I gather I need 2 more, only have 1 right now?

Thanks

Something like HSRP? Each router will need at least 2 interfaces.

Not even sure or acknowledged enough at this point to really understand that **** sheet.

Basically connecting all 3 routers in a triangle like fashion to experiment how redundancy works if one link was to fail.

Do you understand now?
