The multicast boundary specifies subnets where the source traffic entering an interface is filtered to prevent the creation of mroute states on the interface. The multicast boundary can be specified through one standard ACL. However, when providing multicast services via a range of groups per service, an interface could potentially join arbitrary groups and, hence, need arbitrary combinations of ACL rules.
