The method comprises determining whether a first priority associated with the first network device is the highest priority when it is compared with priorities respectively associated with other network devices of the VRRP group. Responsive to determining that the first priority of the first network device is the highest priority, the method continues with causing the first network device to assume a master role in the VRRP group, and establishing a multipoint bidirectional forwarding detection (BFD) head session, wherein the BFD head session indicates that the first network device is action as a head of a multipoint BFD tree."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Fast convergence in VRRP with multipoint bidirectional forwarding detection","description":"A method implemented by a first network device of enabling detection of a failure of a network device acting as a master of a virtual router redundancy protocol (VRRP) group of network devices is disc","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9755958","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.
