Abstract: Techniques are described for suppressing data plane traffic using a service monitoring policy for data plane control. If a service provided to a router becomes nonfunctional, preventing the router from being able to forward traffic to a next-hop device, data plane traffic from client devices on the data plane that requires the use of the nonfunctioning service is suppressed. Additionally, new communication pathways to the router that will use the nonfunctioning service are prevented from being established. Traffic is redirected to another router with a functioning service. Thus, traffic that may normally be directed to the router with the nonfunctioning service and not able to be forwarded (e.g., blackholing of data) can be forwarded to the other router.

Abstract: This disclosure describes techniques for enabling interoperability between asymmetric and symmetric Integrated Routing and Bridging (IRB) modes. An interfacing component may be configured to receive a first route advertisement from a first edge node in a Layer-2 (L2) fabric. The first route advertisement may correspond to an asymmetric format route, for instance. The interfacing component may be further configured to receive a second route advertisement from a second edge node in a L2/Layer-3 (L3) fabric. The second edge node may be configured for symmetric integrated routing and bridging (IRB). The interfacing component may be configured to re-originate the first route and the second route such that the interfacing component is included as a hop in the resultant routes between the L2 fabric and the L2/L3 fabric.
