IPv6 basics: address an interface

Enable IPv6 routing globally on R1. Then bring up Gi0/0 and assign it the global unicast address 2001:db8::1/64.

Topology

R1

Objectives

Hint 1 — order

Enable ipv6 unicast-routing globally BEFORE adding addresses. Otherwise the router treats itself as a host, not a forwarder.

Hint 2 — full sequence

enable
configure terminal
 ipv6 unicast-routing
 interface gi0/0
  no shutdown
  ipv6 address 2001:db8::1/64
  end
