RBE was developed to address the known RFC 1483 bridging issues, including broadcast storms, scalability, and security. RBE features function identically to half-bridging, except it operates exclusively over ATM. Half-bridging works by allowing certain IP address to go over a certain VC; therefore, use Layer 3 addresses instead of ARP to forward to different VCs. By eliminating Layer 2 connectivity between subscribers, RBE can scale well, provide greater performance, and provide better security that RFC 1483 bridging (using IRB) failed to provide.
