A provider edge (PE) network device may detect an L2 forwarding loop on an L2 forwarding path that includes the access-facing logical interface. In response to detecting an L2 forwarding loop and based at least on comparing an identifier for the local PE device and an identifier for a remote PE device that implements the EVPN instance, the PE device may block the access-facing logical interface to block L2 traffic from the local customer network."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Loop prevention for EVPN and PBB-EVPN","description":"In general, techniques are described for reducing forwarding loops for layer (L2) traffic that traverses an EVPN or PBB-EVPN instance (EVI) by deterministically determining an access-facing logical in","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-10469361","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.
