I've done CCNA a long, long time ago at school, and now I need to use it.. But as you know, you forget things quite easly when not using it :P
Ok, I need a router that is able to be connected to 2 WAN ISP's, and be connected to the LAN (duh). So that when one WAN connection failes that the other one will take over, or that they devide the load evenly or something like that.
But now I see the routers comming with ADSL, DSL. I have three connections availible, 1 cable internet, 1 DSL and 1 ADSL. Can anyone explain to me which router is able to take two WAN connections? Or tell me what to do best in this situation?
I see that Cisco has a new series 1800, 2800 etc.. But I come from the 2600 and 3600 series times, so it isn't telling me much.
-- EDIT --
I've spoken to a friend of my in system and networking and he suggested me that it's also possible to use a layer 3 switch. Connecting two ISP to it from the modems and configure it so that it will balance the load on both WAN ports when needed. What is the downfall of using a layer 3 switch instead of a router?
