FreeBSD Configure IPv6 Networking / Static IP Addr

剑心通明

Q.How do I configure
IPv6
networking under
FreeBSD
7.x server? How do I assign IPv6 IP address using command line utility?
A.IPv6 (IP next generation) can be easily configured under FreeBSD 7.x or 6.x. You need to know:
a) Adefault router IPv6address such as 2001:470:1e04:5ea::1
b)128 bit IPv6 IPsuch as 2001:470:1e04:5ea::10
FreeBSD IPv6 Network Configuration
Open /etc/rc.conf file, enter:
# vi /etc/rc.conf
WARNING!Following configuration requires that the
kernel
has been compiled with options INET6 (which is default in FreeBSD 6.x and 7.x)
Append following configurations:
ipv6_enable="YES"
ipv6_ifconfig_fxp0="2001:470:1e04:5ea::10"
ipv6_defaultrouter="2001:470:1e04:5ea::1"
Where,

• ipv6_enable="YES": Turn on IPv6 networking support.
  
• ipv6_ifconfig_fxp0="2001:470:1e04:5ea::10": Assign an IP address
  
• ipv6_defaultrouter="2001:470:1e04:5ea::1": assign a default router

Save and close the file. Restart networking, enter:
# /etc/rc.d/netif restart && /etc/rc.d/routing restart
To view newly assigned IP address, enter:
# ifconfig
# ifconfig | grep inet6
How do I test my FreeBSD IPv6 networking connectivity?
Simply use ping6 or traceroute6 commands, enter:
$ ping6 ipv6.google.com
Try traceroute6 command, enter
$ traceroute6 ipv6.google.com

Try host command to obtian both IPv6 and IPv6 address, enter:
$ host www.kame.net
Sample output:
www.kame.net has address 203.178.141.194
www.kame.net has IPv6 address2001:200:0:8002:203:47ff:fea5:3085
Finally, you can always visit
www.kame.net
and see dancing kame to confirm IPv6. You can also try
IPv6 Google search
.
How do I assign IP address using command line ifconfig utility?
Use ifconfig command as follows to assign an IP address:
# ifconfig {interface-name} inet6 {IPv6-Address} prefixlen {routed-bit}
# ifconfig le0 inet6 001:470:1e04:5ea::10 prefixlen 64
To add a default router, enter:
# route -n add -inet6 default {IPv6-Router-IP}
# route -n add -inet6 default 2001:470:1e04:5ea::1
