Under what scenarios do providers install egress ACLs which could say for
eg.

1. Allow all IP traffic out on an interface foo if its coming from source
IP x.x.x.x/y
2. Drop all other IP traffic out on this interface.

Question seems to be 'when do you need to drop packets', I'm sure 10
different people would give 10 different use-cases.

One use-case for this particular ACL is that the interface is used for MGMT
only, so you allow NMS network and drop everything else.
