RBE: ignoring MAC address?

When RBE is configured on an ATM interface. Design guide tells me that incoming packets are directly forwarded to the IP routing process.

We've configured RBE on a ATM Interface and see every incoming IP packet beeing processed by the IP routing - even if the packet has not a MAC of this RBE interface.

So this RBE interface seems to be in promiscuous mode and processes packets for other IP host as well.


Is it correct that IRB makes a MAC filtering and RBE does not?

Hi,


I never tried what you say, but I can perfectly believe that there is no check on received mac w/ RBE. This way there is less code to execute, and less chances that a misbehaving CPE won't work and cause calls to ISP's customer service.
