The network device may acquire a PW extended index of a PW extended entry in a PW extended table and a private network layer-2 header for the inner IP datagram from an adjacency entry having the adjacency index. By using the private network layer-2 header and a public network label, a private network label and a public network layer-2 header in a PW extended entry having the PW extended index, the network device may encapsulate the inner IP datagram into a L2VPN packet and forward the L2VPN packet through a physical egress interface in the PW extended entry."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Access layer-2 virtual private network from layer-3 virtual private network","description":"In an example, a network device may receive a L3VPN packet of which an egress label edge router (LER) is the network device, and acquire an adjacency index of an adjacency entry in an adjacency table ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-10505759","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.
