For example, a set or routers operating to provide a multi-homed EVPN DCI may utilize adjacency state information learned from a Protocol Independent Multicast (PIM) executing within the underlying transport network of a multi-homed data center to facilitate selection of a designated forwarder for the EVPN between the data centers. By leveraging adjacency state information, an enhanced DF election may be automatically performed for the EVPN to facilitate selection of a designated forwarder in a manner that may avoid loss of traffic in situations where a topology event in the underlying transport network of the data center."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Designated forwarder election for multi-homed data center interconnect using multicast routing protocol state information","description":"Techniques are described for supporting designated forwarder election for a multi-homed Ethernet virtual private network (EVPN) data center interconnect (DCI) between multiple data centers by leveragi","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9628409","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
