Andrei Robachevsky has proposed the following changes to the syntax for policy expressions in RPSLng based on feedback from the list and a desire to simplify the syntax for the case where v4/v6 and/or unicast/multicast policy are converged. 1) the absence of safi in an expression means that both unicast and multicast are defined. I.e., afi ipv4 == afi ipv4.unicast,ipv4.multicast 2) The afi specification will be optional in the mp-* attributes in the aut-num class. If no afi is specified, the policy shall be expanded to include all afi and safi types, namely -- afi ipv4.unicast,ipv4.multicast,ipv6.unicast,ipv6.multicast 3) introduce a pseudo afi with the value of "any". I.e., afi any.unicast == afi ipv4.unicast,ipv6.unicast afi any == afi ipv4.unicast,ipv6.unicast,ipv4.multicast,ipv6.multicast Looking forward to your feedback. Regards, Larry
