Allowed glue is addresses records of nameserver whose names are below the delegating zones. Absolutely, 100% required, when the nameserver's name is within or below the delegated zone and sibling glue which are within or below another another zone delegated from the parent zone. The latter are often but not always required.
Then there are configurations where you need glue from somewhere else in the DNS. No current nameserver supports these anymore as they are unmanageable.
