    摘要： A first network device may receive a first advertisement of a network destination from a second network device and may detect multihoming with the second network device. The second network device may detect the multihoming with the first network device. The first network device and the second network may enable egress protection for the multihoming. The first network device may allocate, from a first pool, a protection group identifier for a group of multihomed network devices and may allocate, from a second pool, a network destination identifier for the network destination. The first network device may provide, to a network and the second network device, a second advertisement that includes the protection group identifier and the network destination identifier. The protection group identifier and the network destination identifier may cause the network to direct traffic for the network destination, via the group of multihomed network devices.

    摘要： This disclosure describes techniques for improving speed of network convergence after node failure. In one example, a method includes storing, by SDN controller, an underlay routing table having routes for an underlay network of a data center and an overlay routing table having a set of routes for a virtual network of an overlay network for the data center, wherein the underlay network includes physical network switches, gateway routers, and a set of virtual routers executing on respective compute nodes of the data center; installing, within the underlay routing table, a route to a destination address assigned to a particular one of the virtual routers as an indicator of a reachability status to the particular virtual router in the underlay network. The SDN controller controls, based on presence or absence of the route within the underlay routing table, advertisement of the routes for the virtual network of the overlay network.
