OSPF: Cannot find next hop for LSA type

[Eugene M. Zheganin]

Hi,

Recenly I occasionally found that one can define the OSPF area twice, like
area 0.0.0.1 {
    interface "eth0";
}
area 0.0.0.1 {
    interface "eth1";
}

And this obviously erroneous configuration passes the bird configuration 
check, and starts causing unpredictable and wierd problems, including 
the one mentioned in subject. Since bird doesn't seem to have a bug 
tracker, this list seems to be an appropriate place to report this.

Thanks.
Eugene.
