If you cannot ping across your IX, you need to look lower than BIRD to figure out the problem.

I can ping the IP through IX 

 

 

I would try to answer questions like: Is ARP resolving IPs to MACs?  

Yes ARP is resolving IPs to MACS

 

Is the problem isolated to a single BIRD server only?  

Yes the problem occurs now on new one I am installing, the other BIRD installed later are working properly 

 

Is it only IPv4 problem only,

Yes it is an IPv4 problem, 

 

or IPv6 as well?

 

If you can answer some of these questions, you'll get closer to finding the root cause, I expect.

 

Cheers,

Jonathan
