In an example, a first member network device of a virtual stack device may an input from a Multi-Active Detection (MAD) device. The virtual stack device may be a logical network device comprising the first member network device and a second member network device. Based on the input from the MAD device, the first member network device may determine whether a grace link state advertisement (LSA) is to be sent to a neighbor Open Shortest Path First (OSPF) enabled router by the first member network device, wherein the neighbor OSPF enabled router is an OSPF neighbor to the virtual stack device."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Grace link state advertisement (LSA) from a virtual stack device","description":"Examples disclosed herein relate to a grace link state advertisement (LSA) from a virtual stack device.
