FW: use Bird as Route Server for Balcan-IX

[Maria Matejka]

Hello!

and I'd suggest using BIRD 2 for now as versions 1.6.x are considered 
legacy; they are not getting any more updates, just security

I'd also suggest at least trying if BIRD 3 could work for you, provided 
you don't need the buggy features, most notably MRT dumping and also 
checking ROA while displaying routes to CLI.

… if you'd like to get some paid support and also support the 
development, the bird-support at network.cz e-mail address is the right 
place to go.

I'd suggest not prefering clock speed any more as BIRD 3 is getting its 
next version really soon. If your load is so high for you to consider 
clock speed, you should probably migrate to BIRD 3 as soon as it gets 
stable for you, thus needing the high core count anyway.
