How much memory is enough in the Lab environment?

Almost. You don't have to clear the bgp neighbor if you've configured bgp
"soft reconfiguration". clear bgp soft reconfiguration (in or out as
appropriate) and it will make the change take effect without clearing your
bgp neighbors. This is a significant timesaver in the lab. The only time
you really wouldn't want to use it is if you don't have enought memory.
