IPv6 Deployment on Cisco IOS-XE: Dual-Stack Config, OSPFv3, and Prefix Delegation

IPv6 is no longer optional. In this hands-on guide, we walk through everything you need to get IPv6 running on Cisco IOS-XE:

• Enabling ipv6 unicast-routing and CEF — the two commands every deployment starts with
• Dual-stack interface configuration with global unicast and link-local addresses
• SLAAC vs stateful DHCPv6 — when to use each and how to configure both
• DHCPv6 Prefix Delegation for enterprise edge and branch deployments
• OSPFv3 in address-family mode with real neighbor and route table output
• IPv6 ACLs — including the ICMPv6 permits you must not forget
• Common gotchas: RA flooding, MTU/PMTUD issues, and DAD failures

Every config block uses verified IOS-XE syntax with real show command output.
