Abstract: In an example embodiment, an apparatus with a first interface coupled to a local domain with routers that employ a redundant router protocol, such as Hot Standby Router Protocol (HSRP) and/or Virtual Router Redundancy Protocol (VRRP), and a second interface coupled with a shared domain, such as Virtual Private LAN (Local Area Network) Service (VPLS), and virtual bridging logic coupled with the first and second interfaces. The virtual bridging logic performs packet snooping, filtering and/or provides a proxy service so that the routers employing the redundant router protocol are localized in the local domain, and avoids the routers employing the redundant router protocol from associating with other routers employing the redundant routing protocol that are in another local domain coupled with the shared domain.

Abstract: In an example embodiment, there is disclosed herein an apparatus comprising an ingress interface, an egress interface, and a storm controller coupled to the ingress interface and the egress interface. The storm controller is operable to determine whether to forward packets for a traffic flow received at the ingress interface to the egress interface based on a rate over a time period. The storm controller forwards packets for the traffic flow while the rate exceeds a first threshold and is less than a second threshold while a predefined condition exits. The storm controller limits traffic for the traffic flow to the first threshold while the rate exceeds the first threshold and the predefined condition does not exist.
