BIRD works with RFC 3021 style addresses without problems, it is just
confused by the fact that directed broadcast address for the iface is
configured to 255.255.255.255, which is address reserved for link-local
broadcast.

BIRD should work without problems on these interfaces (unless you use
broadcast like in RIPv1), it is just warning.

IMHO reasonable setting would be to not set directed broadcast address on
such interfaces. Link-local broadcast address works for any interfaces
and need not be configured.

bird scalability

[Иван Разин]

Hello!

We quite successfully use Bird in our infrastructure and now want to expand
it. I would like to know how it will behave in the following conditions are
met:

4 BGP full view
70 Bird ospf routers in the same area
1 ospf routes

Did someone experience in the deployment of such a scheme and whether there
were any difficulties or problems?

'Aggregate' pipe protocol - is it planned?

[Andrew]

Hi all.

IMHO it'll be good to have 'aggregate' protocol (like 'pipe' one) for 
route count decreasing in system routing table (which results in routing 
performance increase)) and for using bird server as routing server for 
hardware routers/L3 switches which usually have not too big TCAM.


Is such protocol planned for future?
