* IPv6の設定をするに当たりOS毎の設定方法 [#m41995a8]
各OSごとにIPv6のネットワーク設定に違いが大きく、プロトコルにIPv6を指定する場合、-inet6, ipv6 などいろいろとあり、複数のOSを扱っていると混乱するので、まとめる。
** Linux [#Linux]
*** iproute2 command [#Linux_iptable2]
''format''
/sbin/ip -6 <OBJECT>
/sbin/ip -f inet6 <OBJECT>
''example''
show routing table
$ /sbin/ip -6 route list

$ /sbin/ip -f inet6 route list

default via fe80::1 dev eth0.305 metric 1
add static route
# /sbin/ip -6 a add 2001:db8::1/64 dev eth2
# ip -6 a l dev eth2

*** ifconfig [#Linux_ifconfig]
''fomat''
/sbin/ifconfig <interface> inet6 [add|del] <ipv6address>/<prefixlength>

/sbin/ifconfig eth2 inet6 del 2001:db8::1/64
*** route command [#Linux_route]
''format''
/sbin/route -A inet6
/sbin/route -A inet6 [add|del] <ipv6address>/<prefixlength> gw <ipv6gateway>
''example''
add static route
# /sbin/route -A inet6 add 2001:db8:100::/48 gw 2001:db8::2

*** ifconfig [#s6be921a]
''format''
# ifconfig <interface> inet6 <ipv6address>/<prefixlength>
or
# ifconfig en0 inet6 <ipv6address> prefixlen <prefixlength>
# ifconfig <interface> inet6 <ipv6address>/<prefixlength> delete
or
# ifconfig en0 inet6 <ipv6address> prefixlen <prefixlength> delete
IPv6 では、
# ifconfig <interface> inet6 <ipv6address>/<prefixlength> -alias
をつけても同じ挙動(aliasという概念がない)
''example''
# ifconfig en0 inet6 2001:db8::1/64
# ifconfig en0 inet6 2001:db8::3 prefixren 64
# ifconfig en0 inet6 2001:db8::1/64 delete
# ifconfig en0 inet6 2001:db8::3 prefixren 64 delete
*** route [#aa0d2b12]
''format''
# route [add|delete] -inet6 <ipv6address>/<prefixlength> <ipv6gateway>

# route add -inet6 2001:db8:100::/48 2001:db8::1
