Newb Question. Connecting routers with ethernet not serial!

HI. i was thinking about random stuf icon_idea.gif And i was wondering when you connect router to router , people use serial cable and usually set the clock at 64000. thats 64mB/s right?

but if i connected my router with 10/100 ethernet (interface ethernet 0/0) with another router's ethernet interface should i run 100mB at full duplex?

wouldnt that supply a faster data rate??

also can routers perform in full duplex. because to my understand full duplex can be achieved b Switch-Switch Switch-Host and Host- Host using a crossover cable. Can routers be setup with a cross over cable to run full duplex at 100mB/s?

just wondering if people setup their router connection by ethernet instead of serial. and would that supply a faster data transfer rate??

sorry for the newb question

    The clock rate is not the bandwidth. A serial link operates at 1.544 Mbps which would be equivalent to a T1. It is used to emulate a WAN connection so that you can practice WAN protocols like Frame Relay.

    As remyforbes777 stated you are looking at two different technologies.

    One is serial, the other is Fast Ethernet.

    If you were to connect two routers together with a crossover cable and configure the interfaces appropriately, you would be able to establish a 100Mbps Full-Duplex link.

    If you set the speed at 10 but duplex full, you would now have a 10Mbps Full-Duplex link.

    If you set the link at speed 10 duplex half (or speed 100 duplex half) you'd have a slower link even more, because instead of both routers being able to talk at the same time you now have it set so that only one router can talk at a time.

    64000 is 64 kb/second, so your ethernet traffic will slow down when it goes over the serial link. But your 100-meg-full-duplex stuff will still be fast if it goes over one of those interfaces.
