K.2.3.1.1 Hub-to-Hub using Ethernet Switches
Figure K-4. Networking Loop Example
When connecting two or more “hub-sites” where there are multi-paths between each site, care
must be taken to ensure that no Ethernet Networking Loops occur. Figure K-4 shows two hub-
sites connected with two or more modems, where all the traffic being transmitted and received
is on the same LAN/VLAN. Since there is no router in the network and all the traffic is destined
to the same network, an Ethernet Networking Loop has been created.
