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
