You can enable Time Remapping by Right-clicking>Time>Enable Time Remapping (Opt+Cmd+T)
Two things will happen:
1) You'll see two keyframes appear, one for your beginning and one for your end frames
2) You can now extend your layer as long as you want
Leave the where they are and extend your layer by however much you want. Then Opt+Click the stopwatch for Time Remap to add an expression and paste this
This will simply bounce back and forth between those two keyframes for the length of the layer. Now you can scale and position it however you want.

use David's method if you want it to loop forward and then in reverse and then forward again (hence "pingpong") but if you want for any video footage to just loop again and again, you can use the interpret footage dialog in the project window. right click on the footage->interpret footage->main and set the loop to whatever you want (most of us use 99 - it does not cost anything). you can also set the desired frame rate here and experiment in the footage window (click on the footage twice) i.e you don't need to have a composition to experiment.
when you are ready drag the footage to a timeline or create one from the footage itself by right clicking->new comp from selection
