Also, with 1.5.0 I have long OSPF initialization (near 2 minutes - 1.4.5 and
quagga starts much faster). I have OSPF debug log; should I attach it to
mail (does mailing list supports attaches), or should I send it to your
personal mail?
The mailing list accepts attachments, you could send logs there. Also it
would be useful to attach your OSPF configuration. Or you could send it
directly to my personal mail, if you want.
In 1.5.0 there are changes in OSPF initialization, it is much faster in
my test setup but it is possible that there might be some issues in some
border cases. Unfortunately, OSPF initialization is just loosely
specified by RFC 2328 and there are plenty of unspecified details.
I wonder if others have some negative or positive experience with OSPF
initialization (neighbor establishment) in 1.5.0 compared to previous
versions.
Ok, log is in attach.

Config is trivial:

protocol ospf ospf_ua {
     import all;

     area 0.0.0.0 {
         networks {
             192.168.255.64/27;
         };
         interface "vlan1" {
             cost 5;
             type broadcast;
             hello 10;
             retransmit 5;
             wait 40;
             dead count 4;
             authentication none;
             stub no;
         };
         interface "*" {
             stub yes;
         };
     };
}

 From other side, other server with bird-1.5.0 today fetches routes in 
less than minute. Config is almost same (except it has more 
areas/ifaces, and has enabled ecmp):

protocol ospf ospf_mix {
     import all;
     export filter export_OSPF;
     ecmp yes;

     area 0 {
         networks {
             192.168.255.64/27;
         };
         interface "vlan1" {
             cost 5;
             type broadcast;
             hello 10;
             retransmit 5;
             wait 40;
             dead count 4;
             authentication none;
             stub no;
         };
     };
     area 1 {
         networks {
             10.255.193.0/24;
         };
         interface "vlan2" {
             cost 5;
             type broadcast;
             hello 10;
             retransmit 5;
             wait 40;
             dead count 4;
             authentication none;
             stub no;
         };
     };
     area 100 {
         networks {
             10.255.192.0/24;
         };
         interface "vlan3" {
             cost 5;
             type broadcast;
             hello 10;
             retransmit 5;
             wait 40;
             dead count 4;
             authentication none;
             stub no;
         };
     };
