IPv6の設定をするに当たりOS毎の設定方法 †

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 †

iproute2 command †

format

/sbin/ip -6 <OBJECT>
/sbin/ip -f inet6 <OBJECT>

example

show routing table

$ /sbin/ip -6 route list
fe80::/64 dev eth0.305  proto kernel  metric 256
default via fe80::1 dev eth0.305  metric 1

$ /sbin/ip -f inet6 route list
fe80::/64 dev eth0.305  proto kernel  metric 256
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
 3: eth2: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qlen 1000
   inet6 2001:db8::1/64 scope global
      valid_lft forever preferred_lft forever
   inet6 fe80::250:56ff:fe3d:d9b2/64 scope link
      valid_lft forever preferred_lft forever

ifconfig †

format

/sbin/ifconfig <interface> inet6 [add|del] <ipv6address>/<prefixlength>

example

/sbin/ifconfig eth2 inet6 add 2001:db8::1/64
/sbin/ifconfig eth2 inet6 del 2001:db8::1/64

route command †

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
# /sbin/route -A inet6 del 2001:db8:100::/48
# /sbin/route -A inet6 del 2001:db8:100::/48 gw 2001:db8::2

show routing table

$ /sbin/route -A inet6

FreeBSD/MacOS †

ifconfig †

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 †

format

# route [add|delete] -inet6 <ipv6address>/<prefixlength> <ipv6gateway>

example

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