the current document specifies which parameters make up the rule. the only time
a rule would be passed on the wire is for provisioning, it is explicitly
defined in the DHCP option draft.

yes. MAP-T forwards traffic towards a "default prefix", while MAP-E sends to an
address.

if the Rule IPv4 prefix is used to indicate default route 0/0, then there is
nothing to give the IPv4 prefix part. so the complete address is given as a
parameter. this is to help implementations requiring that the next-hop is of
the same address family as the route in the RIB. it will never make it onto the
wire, so strictly speaking it isn't needed. useful for troubleshooting though,
so that you can IPv4 ping your default router.
