Important Points about Shared LAG State Tracking The following is more information about shared LAG state tracking. • This feature is available for static and dynamic LAGs. • Only a LAG can be a member of a failover group. • You can configure shared LAG state tracking on one side of a link or on both sides. • If a LAG that is part of a failover group is deleted, the failover group is deleted. • If a LAG moves to the Down state due to this feature, its members may still be in the Up state. LACP Basic Configuration Example The screenshots in this section are based on the following example topology. Two routers are named ALPHA and BRAVO, and their hostname prompts reflect those names.
