The networking switch includes a virtual router redundancy protocol (VRRP) module configured to perform active interact protocol (IP) forwarding. Moreover, the VRRP module is configured to indicate a status of the networking switch to the second networking switch via the ISL. The status is one of: initialization when the networking switch is not currently active (INIT), back-up status when the networking switch is acting as a back-up switch (BACK-UP), or master status when the networking switch is acting as a master switch (MASTER). In addition, the networking switch is positioned at a boundary between L2 and Layer-3 (L3)."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Active IP forwarding in an event driven virtual link aggregation (vLAG) system","description":"In one embodiment, a networking switch includes an interswitch link (ISL) interface configured to communicate with a second networking switch via an ISL and a networking port configured to connect to ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9716616","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.
