摘要： A method and apparatus is disclosed for providing gateway anycast virtual MAC reachability in extended subnets. When an extended L2 subnet spans more than one geographical location, it is desirable that the gateway MAC addresses learned in each location be the same across all IP hosts. Accordingly, the gateway MAC address may be preserved (i.e., programmed) in more than one port on a bridge, such as both a local port and a LAN extension port. The bridge may forward traffic having the anycast MAC address to the closest instance of the MAC address, rather than replicating the traffic to the multiple ports on which the anycast MAC address is programmed. If the gateway reachable on the local port goes down, the frame may be forwarded to the local gateway in the second layer 2 subnet over the LAN extension port.

摘要： In one embodiment, when a network element is to be removed from or inserted into a network a Graceful Operations Manager schedules graceful shut-down and/or start-up routines for different protocols and/or components on the network element in an optimal order based on dependencies between the different protocols and components. The Graceful Operations Manager communicates with the different components at different stages of their shut-down or start-up process and communicates information on the standby topology across components and/or protocols to enable the synchronization of the standby topology computation on all components and/or protocols that are affected by the removal or insertion.
