Abstract

In one aspect, A computerized method of a gateway distributing routes learned through routing protocols (RP) into a Border Gateway Protocol (BGP) includes the step of providing a first gateway that receives a route over a routing protocol. The method includes the step of with the first gateway, redistributing the route to one or more peer routers as a BGP route based on one or more specified criteria. The method includes the step of setting a gateway precedence based on the redistribution of the route to the one or more peer routers as the BGP route. The method includes the step of, based on the gateway precedence, setting a second gateway to automatically redistribute the route with different priorities to influence steering of traffic to a preferred gateway.

Dependent claims

A method for using routes in an overlay network created over at least one public cloud datacenter in which a gateway is deployed, the overlay network implemented by the gateway and a set of edge devices outside of the public cloud datacenter, the method comprising:

at a location comprising at least one edge device outside of the public cloud datacenter:
receiving a first route through the overlay network that is of a first type and that is translated from a second-type route, and a priority level for the first route;
receiving a second route through the overlay network that is of the first type and that is translated from a third-type route, and a priority level for the second route;
using the received priority levels to determine, for a received packet, whether the first route or the second route is preferable to send the packet to a destination of the packet through the overlay network;
when the first route is preferable, forwarding the packet along the first route to the destination;
and
when the second route is preferable, forwarding the packet along the second route to the destination.
