Abstract: This disclosure describes techniques and mechanisms for disclosure describes techniques and mechanisms for a central management plane to automatically create and assign system identifiers to network devices, thereby creating a global network hierarchy within a network. The techniques enable the use of a system identifier to be automatically generated and assigned, as well as configuration and network policies to be automatically generated based on the system identifier. Accordingly, the techniques enable automation of regional connectivity and policy application, a simplified manner of troubleshooting/debugging of any connectivity issues, and a simplified, aggregated view of statistic and analytics related to problems at site, sub-region, and region levels.

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.

Abstract: Techniques are described for routing traffic through an interconnect cloud gateway based on cloud traffic routing indicators. The interconnect cloud gateway can advertise the cloud traffic routing indicators, which can include cloud indicators and transport gateway indicators. The cloud indicators can include cloud tags utilized to route cloud traffic. The transport gateway indicators can include transport gateway flags utilized to identify private networks utilized to route the cloud traffic. The cloud traffic can routed during normal private network operation through private networks, which can be dynamically replaced by public networks due to occurrences of failures preventing the data traffic from being routed through the private networks and to cloud networks.

Abstract: A method for enabling access to varying route attribute states during routing policy application on network devices. Concerning routing policy configurations, it is currently possible to evaluate network routes based on a singular state of one or more route attributes. In some scenarios, however, access to more than one state of the route attribute(s) is desirable. In addressing these scenarios, the disclosed method introduces state namespaces through which different states of the routing attribute(s) are maintained and accessed.
