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.
