Abstract: A first network device may receive an advertisement that includes a prefix for a second network device, wherein the advertisement is destined for a third network device. The first network device may determine, based on a network topology, whether a next hop is one hop away or multiple hops away. The first network device may selectively modify the advertisement to include a first segment identifier, based on the next hop being one hop away and to generate a first modified advertisement, or may modify the advertisement to include a second segment identifier, based on the next hop being multiple hops away and to generate a second modified advertisement. The first network device may forward the first modified advertisement or the second modified advertisement toward the third network device.

Abstract: A network device may receive policy data identifying a first segment routing (SR) policy and a second SR policy. The first SR policy may be associated with a first path through a network and a first next hop, and the second SR policy may be associated with a second path through the network and a second next hop. The network device may advertise, to another device, reachability associated with the first next hop and the second next hop, and may receive, from the other device, a packet with a header. The network device may determine, from the header, data identifying the first next hop or the second next hop, without performing a lookup, and may cause the packet to be routed to a destination address, via the first path or the second path, based on the policy data associated with the first next hop or the second next hop.

Abstract: A route reflector (e.g., a flex-algorithm optimal route reflector (ORR)) may receive an advertisement communication from a network device of a network associated with the route reflector and may identify, in the advertisement communication, information identifying one or more flex-algorithms that are supported by the network device. The route reflector may determine, based on the information identifying the one or more flex-algorithms that are supported by the network device, a set of routing paths associated with a flex-algorithm of the one or more flex-algorithms. The route reflector may update a data structure to include routing path information that indicates the set of routing paths associated with the flex-algorithm and may transmit a routing communication that includes routing information associated with the routing path information to the network device.

Abstract: 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.

Abstract: In some implementations, a border gateway protocol (BGP) network device may receive from an originator BGP network device via a first other BGP network device, a first message, wherein the first message includes first attribute data associated with a non-transitive attribute, wherein the first attribute data comprises a first metric data element that is associated with a metric data element format and that indicates a metric type, a metric value, and continuity information. The BGP may process the first message to determine first path information associated with a first path from the BGP network device to the originator BGP network device via the first other BGP network device.

Abstract: A network device may receive topology data identifying a spine and leaf topology of network devices, and may set link metrics to a common value to generate modified topology data. The network device may remove data identifying connections from leaf network devices to any devices outside the topology from the modified topology data to generate further modified topology data, and may process the further modified topology data, with a model, to determine path data identifying paths to destinations. The network device may determine particular path data identifying shorter paths and longer paths to corresponding destinations, and may determine hop counts associated with the paths. The network device may determine whether the hop counts are all odd values, all even values, or odd and even values, and may perform actions based on whether the hop counts are all odd values, all even values, or odd and even values.

Abstract: In some implementations, a first network device may receive an advertisement from a second network device. The advertisement may be associated with indicating that the second network device is configured to support a particular flex-algorithm. The first network device may identify, in the advertisement, an address of the second network device. The first network device may configure a routing table of the first network device to indicate that the second network device is capable of receiving traffic associated with the particular flex-algorithm based on the address. The first network device may perform, using the routing table, an action associated with routing the traffic associated with the particular flex-algorithm.
