Description: Proprietary extensions for the rfc1156 defined ipRoutingEntry. A proprietary ipRouteEntry entry contains 10 standard objects and the proprietary object listed below. The standard objects are: ipRouteDest, ipRouteIfIndex, ipRouteMetric1, ipRouteMetric2, ipRouteMetric3, ipRouteMetric4, ipRouteNextHop, ipRouteType, ipRouteProto and ipRouteAge. To add an atEntry to the ipRoutingTable, MIB-II defines the ipRouteType as the validating item. Therefore, ipRouteType must be the last item in the message when adding an entry. All items, both proprietary and standard, except the ipRouteDest, ipRouteNextHop, ipRouteMetric1, and ipRouteType are determined by the agent. To add to the ipRouteEntry the agent requires the ipRouteDest, ipRouteNextHop, and the ipRouteMetric1 followed by the ipRouteType. The ipRouteIfIndex is determined by the agent based on the ipRouteDest. The ipRouteMetric2, ipRouteMetric3 and ipRouteMetric4 are not used by the router and are set to zero. The ipRouteProto is set to local and rRtStatic is set to static. All ipRouteEntries manually defined are considered static and are not removed by the agent until specifically requested by the manager. If the ipRouteMetric1 is not provided, it's value defaults to 1. To remove an ipRouteEntry, the ipRouteType should be set to invalid. The INDEX value specified should correspond to the destination IP address of the desired entry.
