7.3.7 Realm_List Table

This table is used to configure Realms of the Home network and supported Roaming networks. The configured Home network Realm identifies an egress Diameter Message generated by the Home network, which is sent to a foreign network. This table is also used to customize the behavior of Origin Realm and Destination Realm Whitelist Screening (RealmWLScr) countermeasure.
