+Dataplane Commands
+==================
+
+The zebra dataplane subsystem provides a framework for FIB
+programming. Zebra uses the dataplane to program the local kernel as
+it makes changes to objects such as IP routes, MPLS LSPs, and
+interface IP addresses. The dataplane runs in its own pthread, in
+order to off-load work from the main zebra pthread.
