Hello, Freebsd-net.
"Famous" dedicated server provider Hetzner provides native IPv6 for
servers, but with rather strange routing configuration: you need to
configure static interface route and make this route default.
If I add such lines in /etc/rc.conf:
ifconfig_re0_ipv6="inet6 2a01:4f8:131:60a2::2 prefixlen 64 auto_linklocal
accept_rtadv"
ipv6_static_routes="ipv6defgw"
ipv6_route_ipv6defgw="2a01:4f8:131:60a0:: -prefixlen 59 -iface re0"
ipv6_defaultrouter="2a01:4f8:131:60a0::1"
ipv6_default_interface="re0"
It doesn't work, because default route added first and it fails to
be added, as route to 2a01:4f8:131:60a0::1 is not known yet.
If I replace this line in /etc/rc.d/routing:
ipv6_static_routes="default ${ipv6_static_routes}"
with
ipv6_static_routes="${ipv6_static_routes} default"
Everything works, but it is ugly hack -- to change system startup
script, and I don't like it (for FreeBSD 8 I needed to change
/etc/network.subr in similar way).
Is here any good way to configure such routing without changes in
scripts, only with /etc/rc.conf?
Hi Lev,
just use another static route instead of the ipv6_defaultroute entry:
ipv6_static_routes="ipv6defgw ipv6defgwroute"
ipv6_route_ipv6defgw="2a01:4f8:131:60a0:: -prefixlen 59 -iface re0"
ipv6_route_ipv6defgwroute="default 2a01:4f8:131:60a0::1"
It's not pretty but works without having to modify the rc scripts.
Greetings,
Sascha
