摘要： According to one embodiment, a method includes receiving, by a first edge device at a first site, a first site overlay control plane message including control plane information. The first edge device translates the first site overlay control plane message into a core overlay control plane message. The first edge device sends the core overlay control plane message over a core network to a second edge device at a second site.

摘要： Systems, methods, and other embodiments associated with logically partitioned networking devices are described herein. One example method includes receiving a message from a common interface. The message comprises a logical partition header (LPH) and a network segmentation header (NSH). The LPH may be associated with a logical partition of a networking device. The NSH is associated with a grouping (e.g., segmentation) of networking devices. The example method may also include forwarding the message to the grouping of networking devices based, at least in part, on the NSH and a virtual route forwarding (VRF) table. Forwarding the message to the logical partition of the networking device based, at least in part, on the LPH.

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.

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： Devices, methods and instructions encoded on computer readable medium for implementation of a dual-adjacency between edge devices of a network site. A first edge device comprises one or more local interfaces configured for communication, via a local network, with one or more network devices co-located in a first network site. The first edge device also comprises one or more overlay interfaces configured for communication, via a core network, with one or more network devices located in one or more other network sites connected to the core network. The first edge device comprises a processor configured to establish, via at least one of the local interfaces, a site communication channel with a second edge device co-located in the first network site. The processor is further configured to establish an overlay communication channel, via at least one of the overlay interfaces, with the second edge device.
