This attribute specifies the RIP interface on the virtual router which
routes are exported onto as a result of matching this export policy.
If the attribute advertiseStatus is set to block, then the value of
outInterface is ignored. The outInterface value is not used to select
which routes to block or send, but rather where to export the routes.
A value of 0.0.0.0 indicates that the routes are exported to all RIP
interfaces on the virtual router. Otherwise, the value of this attribute
must match the interface address of a LogicalIf that has a RipIf on the
same virtual router.
