Hi all,
I have an OpenBSD router that sends out router advertisements on the main network, my FreeBSD machine gets a public IPv6 as it's supposed to get. Now I've set up a VLAN on both machines for a VPN transfer net. When I tested that with manually set addresses, it worked as expected. Now I wanted the transfer net to also distribute IPv6 automatically (but internal addresses, fd00::/8), so I added the VLAN interface on the router to the router advertisement daemon. On the FreeBSD machine, the VLAN interface gets this advertisement or solicits for it with rtsold, either way, it gets the IPv6 addresses as expected. What's missing however is any kind of route entry. When I add the addresses manually to the interface, the routing table gets populated with the appropriate network entries, but with the automation they are missing. On the "regular" LAN it works as expected.
ifconfig:
netstat -rnf inet6
As you can see, the entry for the fd4b:5320:4954:eeee::/64 network is missing, and the addresses are marked "detached" in ifconfig.
rad.conf on OpenBSD:
Playing around with the options, esp. prefix and default router shows no difference.
Any help is appreciated, thanks!
