最初に、ルータの設定を行います、まず、現在のIPv6アドレスの状態を確認します。
# show ipv6 address
LAN1 scope-id 1 [up]
Received: 11 packets 1112 octets
Transmitted: 11 packets 1104 octets
link-local fe80::2a0:deff:fe09:352a/64
link-local ff02::1/64
link-local ff02::2/64
link-local ff02::1:ff09:352a/64
PP[01] scope-id 2 [down]
Received: 0 packet 0 octet
Transmitted: 0 packet 0 octet
link-local ff02::1/64
link-local ff02::2/64
#
次に、LAN1インターフェースにIPv6アドレスを設定します。この例では、LAN1インターフェースにグローバルアドレスの3ffe:5ff:100:aa01::1を設定します。
# ipv6 lan address 3ffe:5ff:100:aa01::1
# show ipv6 address
LAN1 scope-id 1 [up]
Received: 63 packets 4856 octets
Transmitted: 48 packets 3960 octets
global 3ffe:5ff:100:aa01::1/64
link-local fe80::2a0:deff:fe09:352a/64
link-local ff02::1/64
link-local ff02::2/64
link-local ff02::1:ff00:1/64
link-local ff02::1:ff09:352a/64
PP[01] scope-id 2 [down]
Received: 0 packet 0 octet
Transmitted: 0 packet 0 octet
link-local ff02::1/64
link-local ff02::2/64
#
次に、Plug and Playのために必要となる、RA(Router Advertisement)の送信の設定をします。
# ipv6 prefix 1 3ffe:5ff:100:aa01::1
# ipv6 lan rtadv send 1
#
ルータの設定は以上です。

ff02::1はリンクローカル・オールノードマルチキャストアドレスです。インターフェースとして指定されているed1と同一リンクにあるノードにICMPv6を送信します。
