This read-write field configures how frames sent to the reserved bridge multicast address 01:80:C2:00:00:03 are treated on the Ethernet flow point associated with this CPD profile. Since this address falls in the range bridges reserve for control protocols rather than user data, the chosen disposition tells the node whether to intercept, drop, or tunnel such frames through the carrier network. As an example, an operator provisioning a business Internet access flow point might set this to peer so any frames a connected device sends to that address are locally terminated and processed instead of relayed onward.
