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

Figure 3-7 shows 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.

Figure 3-7. Hub-to-Remotes with Standard Traffic using Routers or Switches

A wired-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.

A wired-around Ethernet redundancy example for the CDM-710G user is shown Figure 3-9.

Whe

n 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.
