I have a bed of bamboo that is getting out of control (4'x4') and is
encroaching on the neighbor's fence. Attempts to dig it up has failed,
very tough root ball that reaches deep and wide and I need to get rid of
it.

I am thinking of using ROUND UP to kill it.

Will it?

How far will it go? Will it reach beyond the 4'x4' area and poison other
plants nearby or can I do it in such as way to contain it's influence?

Round Up will only kill what you spray it on. If the spray does not hit the
other areas they will be safe.
If you brush it on one plant, the one next to it is usually safe.
