Abstract: Methods, systems and computer readable media for default gateway redundancy support across SPB networks are described. In some implementations, the method can include enabling peer network information exchange on a per-network basis between a plurality of switches in a network and advertising a first address and a second address from each switch in the plurality of switches to the other switches. The method can also include storing, at each switch, the first address and the second address received from the other switches in the plurality of switches. The method can further include routing, at a first switch, traffic for a second switch when the first switch detects that the traffic can be routed more efficiently without being sent to the second switch.

Abstract: Methods, systems and computer readable media for L2 redirection in multi-chassis link access group (LAG) environments are described. In some implementations, the method can include determining, at a core switch, a failure of a link in a split multi-link trunk (SMLT), and building, at the core switch, a table mapping each destination media access control (MAC) address to an incoming split multi-link trunk port. The method can also include sending, from the core switch, a link layer discovery protocol (LLDP) redirect message on a per-destination MAC address and per-source access switch basis. The method can further include maintaining a same mapping for each MAC address not hashed to a cluster peer with the failed link or being mapped to a non-inter switch trunk (IST) port.

Abstract: Methods, systems and computer readable media for network service type and mode advertisement are described. In some implementations, a method can include providing a network service having a service mode and a service type, and generating a network service advertisement message including a service identifier, a service mode portion and a service type portion. The method can also include populating the service mode portion with a first value corresponding to a service mode of the network service and populating the service type portion with a second value corresponding to a service type of the network service. The method can further include forwarding the network service advertisement message from a first system to one or more other systems via a network.

Abstract: Methods, systems and computer readable media for network migration as described. The method can include receiving, at a processor, an indication to initiate a migrate start. The method can also include initiating, at the processor, a migrate start including forwarding traffic in a first protocol based on a first table while building a second table to forward traffic in a second protocol different from the first protocol. The method can further include performing a migrate cutover when it is determined that one or more MAC addresses for an active session have been learned and stored in the table. The method can also include completing a migration when an indication is received to complete the migration. The method can also include aborting the migration based on a received indication to abort the migration.
