The first PE further generates a CE MAC table in the VPN instance according to the stored topology information and bridging MAC addresses of the another PE; calculates a unicast minimal spanning tree by taking the first PE as a root, generates a unicast MAC table in the VPN instance according to the unicast minimal spanning tree. Each PE further selects one of the PEs in the VPN instance as a root bridge, calculates a broadcast minimal spanning tree by taking the root bridge as a root, and generates a broadcast MAC table in the VPN instance according to the broadcast minimal spanning tree."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Provider edge in virtual private LAN service network","description":"In a VPLS network, a first PE in a VPN instance sends topology information and a bridging MAC address of the first PE to another PE in the VPN instance, receives and stores topology information and br","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9705788","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.
