Hi!

On a OpenBSD 4.6 router we have moved an IP from one VLAN to another.
First we moved the IP to the other interface and after that we removed
the old VLAN interface. Now we notice that the old link stays in the
OSFP fib.

ospfctl sh fib

....

*C        0 xx.yy.233.160/28   link#62
 C        4 xx.yy.233.160/28   link#27

....

link #62 is the new VLAN interface, link #27 is the old VLAN inteface.
What's happening here? How can this be resolved?

Regards,

Peter

Sorry you need to upgrade to 4.7 or restart ospfd. Versions before 4.7
were easily confused by interface changed. In 4.7 it may be necessary to
reload the config after certain changes to sync the config with the
network setup.

Oops, do i loose the OSPF learned routes in the routing table if I
restart ospfd?

Though I think interfaces should be rescanned every time ospfd send a
message isn't it?

No, that would require way to much resources. ospfd is keeping track of
interfaces but in the 4.6 version there was a bug in the tracking code
which is causing these issues. Not to many people seem to change
interfaces to often so that problem remained undetected for a rather long
time.
