With IPHost Network Monitor you can run simple snmp requests against a Nortel device in your network.
vrIpRipExportOutInterface
Virtual Router Ip Rip Export Out Interface
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.
