Abstract: A method for initializing the border gateway protocol (BGP) on network devices. The method includes initializing, by a first network device, a BPG session with a second network device. The method further includes receiving, by the first network device from the second network device, route updates and an end of routing information base (EOR) marker. The method further includes updating an n_EOR variable maintained by the first network device after receiving the EOR marker and, after updating the n_EOR variable, determining that the first network device has received route updates from all peer network devices, and subsequently updating, in the first network device, a routing information base (RIB) using route updates received from the peer network devices. The method further includes updating, in the first network device, a forwarding information base (FIB) using the updated RIB and advertising, to all peer network devices by the first network device, routes.

Abstract: First and second network devices may be configured to multihome a host. The first network device may advertise a first MAC and IP advertisement route indicative of a first link between the first network device and the host. The second network device may advertise a backup MAC and IP advertisement route indicative of a second link between the second network device and the host. Based on the backup MAC and IP advertisement route, the first network device may store a backup path for reaching the host via the second network device. After failure of the first link, the first network device may forward traffic destined for the host based on the stored backup path.

Abstract: A method for synchronizing a binding process among a group of network devices connected to a server that is multi-homed to the group of network devices in provided. The method is executed by a first network device among the group of network devices and includes: receiving, from the server, network traffic associated with a host executing on the server; configuring, using the network traffic, a binding between the first network device and the host and setting a binding status of the first network device for the host to a first status; and transmitting, in response to the setting and via an out-of-band (OOB) channel to a second network device among the plurality of network devices, first binding instructions for causing the second network device set a binding status of the second network device for the host to a second status different from the first status.

Abstract: Embodiments described herein relate to techniques for designated forwarder (DF) elections, which may include: obtaining DF candidates that are part of a supplementary broadcast domain (SBD), wherein the DF candidate is one of the plurality of DF candidates for the SBD; performing a SBD DF election process to determine an SBD DF winner from among the DF candidates; making a first determination that the DF candidate is not the SBD DF winner; making second determination that a first broadcast domain (BD) provisioned on the DF candidate is not provisioned on the SBD DF winner; excluding the first BD from a set of BDs that are also provisioned on the SBD DF winner; performing additional DF election processes for each BD of the set of BDs; and processing multicast traffic based at least in part on the SBD DF election process and the additional DF election processes.

Abstract: In one embodiment, a method is provided. The method includes determining that a network device should use an underlay multicast group associated with an overlay multicast group for multicast traffic. The underlay multicast group carries multicast traffic for the overlay multicast group. The overlay multicast group is associated with a virtual private network. The method also includes determining an underlay multicast group address for the underlay multicast group. The overlay multicast group is associated with an overlay multicast group address. A first portion of the underlay multicast group address is a function of the overlay multicast group address. The method further includes forwarding one or more multicast packets to one or more multicast receivers via the underlay multicast group using the underlay multicast group address.

Abstract: A network element is provided. The network element includes a tunneling endpoint having a virtual address. The tunneling endpoint is configured to receive an address resolution reply that has a destination MAC (media access control) address matching the virtual address of the tunneling endpoint and is from a network device in a first network that includes the tunneling endpoint. The tunneling endpoint is further configured to send the address resolution reply via an interconnect to a further tunneling endpoint in a further network. A method for address resolution in virtual extensible networks is also provided.
