I came across this ACL command during the course of my studies and didn't understand it. Up until I saw this I hadn't seen anything above the multicast range be used as the destination address in an ACL. What traffic would this identify? How would this affect an inbound distribute list?
access-list 101 permit ip 10.10.0.0 0.0.0.0 255.255.224.0 0.0.0.0
That's for filtering a supernet 10.10.0.0/19
Much easier to write it as a prefix list
