Abstract
A system and method for prioritized multipath access to cloud platform subnets from a software-defined wide-area network (SD-WAN) branch device. In one embodiment, a method includes determining routes to one or more virtual private cloud subnets hosted by a cloud service provider, prioritizing the routes based on one or more factors, and advertising the routes and route priorities over a Border Gateway Protocol session to one or more SD-WAN router appliances.
Claims17
A method, comprising:
- determining a route to a virtual private cloud subnet hosted by a cloud service provider;
- determining a region associated with the virtual private cloud subnet;
- determining a route priority based on the determined region;
- and
- advertising the route and the route priority over a Border Gateway Protocol session to one or more Software Defined Wide Area Network (SD-WAN) router appliances, wherein advertising the route and the route priority further comprises advertising a local-region route with a lower Multi Exit Discriminator (MED) value than a remote-region route.
A system, comprising:
- one or more processors;
- and
- one or more computer-readable non-transitory storage media comprising instructions that, when executed by the one or more processors, cause one or more components of the system to perform operations comprising:
- determining a route to a virtual private cloud subnet hosted by a cloud service provider;
- determining a region associated with the virtual private cloud subnet;
- determining a route priority based on the determined region;
- and
- advertising the route and the route priority over a Border Gateway Protocol session to one or more Software Defined Wide Area Network (SD-WAN) router appliances, wherein advertising the route and the route priority further comprises advertising a local-region route with a lower Multi Exit Discriminator (MED) value than a remote-region route.
One or more computer-readable non-transitory storage media embodying instructions that, when executed by a processor, cause performance of operations comprising:
- determining a route to a virtual private cloud subnet hosted by a cloud service provider;
- determining a region associated with the virtual private cloud subnet;
- determining a route priority based on the determined region;
- and
- advertising the route and the route priority over a Border Gateway Protocol session to one or more Software Defined Wide Area Network (SD-WAN) router appliances, wherein advertising the route and the route priority further comprises advertising a local-region route with a lower Multi Exit Discriminator (MED) value than a remote-region route.
