9.3.3 Hub and Spoke Ethernet Circuit Provisioning
This section provides steps for creating a hub and spoke Ethernet circuit configuration. The hub and
spoke configuration connects point-to-point circuits (the spokes) to an aggregation point (the hub). In
many cases, the hub links to a high-speed connection and the spokes are Ethernet cards.
