Abstract
Techniques for ensuring symmetric forwarding between disparate networks. The techniques may include receiving a gateway preference order associated with a route advertised by an edge node, the edge node associated with a first network. The techniques may also include determining, based at least in part on the gateway preference order, that a gateway node is a more preferred gateway for the route than another gateway node, the gateway node configured to facilitate communications between the first network and a second network. In some examples, the techniques may also include converting the gateway preference order into a metric associated with an IP routing protocol that is in use in the second network. In some examples, the route including the metric may be distributed within the second network such that the gateway node is the more preferred gateway for return traffic of the route.
