Abstract
Methods are provided for ensuring that a service node selects a local leaf node to reach remote destinations by leveraging reverse metric to inform the active service node of the topology of the leaf nodes. The methods involve obtaining connection information about a service node. The connection information indicates whether the service node is locally connected or connected via a virtual private network (VPN) tunnel. The methods further involve generating a reverse metric signaling based on the connection information. The reverse metric signaling includes a different metric value for the service node when the service node is locally connected than when the service node is connected via the VPN tunnel. The methods further involve providing the reverse metric signaling to the service node to cause the service node to select an intermediate network device from among a plurality of intermediate network devices to forward data traffic to a destination.
