Control plane functionalities are provides via SDN controllers or via standard
IP routing protocols. SDN support is provided by using the NETCONF/YANG protocol
for network management, control and telemetry.
Routing is supported via synchronization of the IP FIB and the IP RIB as implemented

below one example of IGP routing via OSPF for IPv6.

The VPP IP FIB can be controlled and updated by one FRR routing protocol which
is used for routing over locators and also over hICN name prefixes.
