+# Description of the YANG Data Model for BGP Topology
 
 The abstract (base) network data model is defined in the "ietf-network" module of {{!RFC8345}}. The BGP-topology builds on the network data model defined in the "ietf-network" module {{!RFC8345}}, augmenting the nodes with BGP information, which anchor the links and are contained in nodes.
