Abstract: Techniques are disclosed for computing a cost of an advertised route to a next-hop network device along a path to a destination based at least in part on a preference for the path. In one example, a computing system computes a cost of a route to a next-hop network device along a path to a destination. The computed cost is based at least in part on (1) a metric for the route and (2) a preconfigured preference for the path. In some examples, the preference for the path is based at least in part on (a) a type of the path as compared to other types of other paths to the destination or (b) a latency of the path as compared to other latencies of the other paths. The computing system sends a route advertisement for the route that includes data indicative of the cost of the route.

Abstract: A network device is configured to associate a tenant of a plurality of tenants with a virtual routing and forwarding (VRF) instance of a plurality of VRF instances. The network device receives a packet comprising metadata specifying a tenant identifier for the tenant. The network device identifies, based on the tenant identifier specified by the metadata, the VRF instance associated with the tenant. The network device retrieves one or more routes from a routing information base (RIB) of the VRF instance associated with the tenant and forwards the packet toward a destination via the one or more routes.

Abstract: Techniques are described for a router providing metric-based multi-hop path selection. For example, a first router of a plurality of routers receives a plurality of network performance metrics for a plurality of links interconnecting the plurality of routers. The plurality of links form a plurality of multi-hop paths through the plurality of routers to a service instance. The router determines, based on the plurality of network performance metrics for the plurality of links, an end-to-end performance of each of the plurality of multi-hop paths. The router selects a multi-hop path over which to forward traffic associated with the session based on the end-to-end performance of each of the plurality of multi-hop paths and one or more performance requirements for a service associated between a session between a client device and the service instance. The router forwards the traffic to the service instance along the selected multi-hop path.

Abstract: Techniques are disclosed for promulgating service information and topology information in a network in a high availability manner. An example device is configured to create a first service and topology exchange protocol (STEP) document. The first STEP document includes service information and topology information. The example device is configured to send the first STEP document to a first STEP repository for forwarding to at least one subscribing network device. The example device is also configured to send the first STEP document to a second STEP repository for forwarding to the at least one subscribing network device.
