3.3.4 Hub-to-Hub with Standard Traffic using Routers

Figure 3-4shows two hub-sites connected with standard Ethernet traffic, using routers instead of switches for Ethernet connection. The routers will block the broadcasts coming from the remote network. 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 3-5. 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 is shown for the CDM-700 User in Figure 3-6. When the CRS-300 1:10 Redundancy Switch backs-up a faulted Traffic Modem, the physical port on the router needs to change from the Traffic Modem port to the Redundant Modem port. Because of this, special router configuration is required for successful operation – the User may need to consult with the router manufacturer.

The wired-around redundancy approach is not recommended.
