3.3.5 Hub-to-Remotes with Standard Traffic using Routers or Switches

Figure 3-7shows hub-to-remotes configuration with standard Ethernet traffic using routers or switches. The routers/switches will block broadcasts coming from the hub and remote networks. Therefore, no broadcast storm can be created or the possibility of having a remote MAC on the Hub networks.

Awired-thru Ethernet redundancy example is shown in Figure 3-8. When the CRS-300 1:10 Redundancy Switch backs-up a faulted Traffic Modem, the physical port, (on the router) does not change because the Ethernet connection is properly rerouted within the CRS-300 from the Traffic Modem to the Redundant Modem.

Awired-around Ethernet redundancy example for the CDM-700 User is shown Figure 3-9. When the CRS-300 1:10 Redundancy Switch backs-up a faulted Traffic Modem, the Dwitch will learn the new MAC address of the redundant unit and traffic will be passed again. This type of architecture will slow down the switching time, because the Switch will need to re-learn the correct port connection.
