About stability: OS interface, BIRD core and BGP should be pretty stable,
OSPF is a fairly complex thing to debug, so although Ondrej is putting
a lot of effort to fixing its bugs, it should be reasonable stable, but
not production quality.

They seem, but they aren't :-)  "show route all" should dump everything
known about all the routes.

Yes, sometimes me :-)  Not in production environment, just for testing and
amusement on my home network

For a large transit site, it surely is, but for any site providing no transit
traffic and only importing other's routes and exporting its own network
statically (which is a fairly common setup), it isn't needed at all.

For all protocols: tested with Cisco and GateD.

As a co-author of BIRD, I hope I'll not have to wear asbestos, but I think
the only routing deamon comparable with BIRD is Zebra -- it has many features
BIRD lacks and has undergone much more testing, anyway I think BIRD is better
designed and offers a very powerful configuration and filtering language (while
Zebra is mimicking almost all brain damaged stuff in Cisco).
