BGP setup and Layer-3 topologies

This section provides diagrams and information regarding BGP setup and Layer 3 topologies.

Figure 2.2, “Layer-3 Topology (Physical Underlay Network)” shows an example underlying network infrastructure.

Figure 2.3, “Layer-3 Topology (Virtual Overlay Network)” shows an example MidoNet virtual network overlaid on top of the underlying network architecture, along with BGP route-advertisement information.
