3 hands-on SLAAC scenarios you build in your own Cisco Modeling Labs instance and grade against the answer key. SLAAC configuration and troubleshooting practice for CCNA and CCNP.
Build an enterprise-clean dual-stack site end-to-end. IPv4 is complete and forwarding on day start; you will deploy IPv6 across the same topology. Enable IPv6 routing, assign prefixes, bring up OSPFv3 with explicit router-ids, keep the access LAN autoconfiguring via SLAAC with stateless DHCPv6 for DNS, and enforce an IPv6 ACL to allow one client flow to the server while denying another. Verify from the hosts and troubleshoot like a real operator.
Build a compact branch LAN where IPv6 hosts already form SLAAC addresses from router advertisements, then add stateless DHCPv6 to supply DNS server and domain-name. You will keep SLAAC for addressing, flip the RA 'other-config' flag so hosts know to ask, and bind an IPv6 DHCP pool with DNS options to the user LAN. IPv4 is prebuilt as a baseline and must keep forwarding. Verify from hosts and the router’s IPv6 DHCP/ND views.
Single-site IPv4/IPv6 lab where IPv4 is already working. You will enable IPv6 routing on the router and place a single /64 on the user LAN so two hosts autoconfigure via SLAAC. Then verify each host’s chosen IPv6 address and the learned default route via the router’s link-local address, and test end-to-end IPv6 connectivity.
