RBE: ignoring MAC address?

Unanswered Question
May 4th, 2008

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?

I have this problem too.

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.
