Abstract
An extended Routing Policy Specification Language (RPSL) permits registry of independent routing policies for different Internet Protocol versions, while being compatible with existing RPSL. Address family identifiers (afis) for identifying a protocol version are inserted into attributes of objects that carry IP address prefixes. RPSL is also extended to permit separate handling of multicast routing policies in any protocol, by including subsequent address family indicators (safis).
