Bridging

Overview

Bridging is used between an OmniSwitch device and a 7450 ESS to create a fast ring. The fast ring bridges the end-user devices, such as BTV set-top boxes, and Layer 2 services, such as VPLS, that distribute multicast traffic. If required, you can configure the devices with MSTP or another STP.

STP is active by default on an OmniSwitch. The default mode of operation is 1x1 mode using RSTP. A loop-free network topology is automatically calculated based on default STP switch, bridge, and port parameter values.

Additional OmniSwitch configuration such as enabling and configuring OmniSwitch learned port security parameters for VLAN ports, DHCP relay, and DHCP snooping can be done while configuring other bridge parameters.

You can configure MVRP as part of the bridging configuration on the OmniSwitch. MVRP provides a mechanism to maintain the contents of dynamic VLAN registration entries for each VLAN, and to propagate that information to other bridges.

In the NFM-P, a bridge is represented in the network view below a device, similar to the routing instance of a device.
