vrIpBgpRouteThrottleLimit
Virtual Router Ip Bgp Route Throttle Limit
This attribute specifies the maximum number of routes in the IP forwarding table this Bgp component instance will process at one time to decide if a route in the IP forwarding table should be exported to a peer. This limit is used for the throttling and is made configurable because the throttling requirements will be different under different network configurations. The default value is 250.
