Configure DHCPv6 Stateless Client

The Stateless Client can automatically learn about any gateway router(s) on the LAN via
router solicitation. It can then dynamically add associated default route(s) into its routing
table via the next-hop link-local address of the gateway router.

From RFC 4864, section 5.5.3: If the sum of the prefix length and interface identifier length
does not equal 128 bits, the Prefix Information option must be ignored.

The effect is that prefix information received in an RA will not be applied to form an IPv6
address via SLAAC if the prefix is greater or less than 64. Since EUI is 64 bits in length the
IPv6 Prefix of the advertising device must be 64 bits as well.

For command information, see the

ipv6 address autoconfig

command on the Stateless

Client.

Note bold configuration command entries show hostnames and interfaces.
Also note the default VLAN interface vlan1 is applied to all ports on a device.
