Hello,
I like to disable linklocal IPv6 addresses on my host, running FreeBSD
9.0-RC3.
I already set net.inet6.ip6.auto_linklocal in /etc/sysctl.conf.
# sysctl net.inet6.ip6.auto_linklocal
net.inet6.ip6.auto_linklocal: 0
Even after a reboot, this does not seem to have any effect. Here is the
config on one interface:
% ifconfig em3
em3: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
options=219b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,
TSO4,WOL_MAGIC>
ether 00:00:24:ce:69:ef
inet 172.25.129.1 netmask 0xffffff00 broadcast 172.25.129.255
inet6 fe80::200:24ff:fece:69ef%em3 prefixlen 64 scopeid 0xc
inet6 2001:610:xxxx:xxxx::1 prefixlen 64
nd6 options=21<PERFORMNUD,AUTO_LINKLOCAL>
media: Ethernet autoselect (1000baseT <full-duplex>)
status: active
Did I overlook something? Is there perhaps a per-interface option I need
to configure in /etc/rc.conf?
The link-local addresses don't really harm, but I found them confusing,
as the host is running as a router, and rtadv announces the link-local
address by default.
Thanks for any help,
Freek
