Re: IPv6: can a link-site (or global) address be configured in rc.conf?

[Bill Fenner]

Bruce is right that machines expect to learn their prefixes from their
local router; however if you're just playing around you might want to
set it yourself.  The easiest way I've found to do this is to say that
this machine is a router:

# sysctl -w net.inet6.ip6.forwarding=1
net.inet6.ip6.forwarding: 0 -> 1

and then run "prefix" to set a site-local prefix:

# prefix dc0 fec0:0:0:1::
# ifconfig dc0
dc0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
        inet6 fe80::2a0:ccff:fe36:7410%dc0 prefixlen 64  scopeid 0x1
        inet6 fec0::1:2a0:ccff:fe36:7410 prefixlen 64 

Of course, if you have global address space too you can assign that prefix
too.
