An OSPF to EGP export rule. Each rule is keyed by
the Autonomous System of the EGP neighbor, the IP
network of the OSPF route in the routing table, and
the Autonomous System from which the route was
learned. The neighbor (to) AS can be set to a wild
card as can the IP network and the (from) AS. The
route is either accepted to be advertised to the
neighbor or discarded from being advertised, and its
metric is applied according to the rule. The best
match is as follows:
