CCNA Foundations: Link-Local & Neighbor Discovery

A focused, enterprise-clean IPv6 day in a progressive CCNA series. You will enable IPv6 on a single user LAN, assign a deterministic link-local gateway, and observe Neighbor Discovery (ND) in action. IPv4 is already working; your job is to turn on IPv6 unicast routing, add a global unicast /64 to the gateway interface, and set an explicit link-local address so hosts learn a predictable next-hop. You will verify SLAAC-derived host addresses, default routes learned via RA, and ND neighbor tables on the router, and then test by pinging both the router’s link-local and global addresses from the hosts.

CDP Neighbor Discovery and Edge Suppression

Enable Cisco Discovery Protocol (CDP) on R1 to map directly-connected Cisco neighbors while suppressing CDP advertisements on the untrusted management-edge interface. Routers are directly cabled for true CDP adjacency and also share a common management LAN via SW1 alongside an Alpine MGMT host.
