Hold time expired error

[Ajai Kumar]

Dear All,


I am suspecting issue on bird,pls refer response are

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


Ans: Yes I can ping the IP from switch connected to bird server. However
not able to ping from bird server.



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

Ans: Yes ARP is resolving IPs to MACS



Question: 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

 Question:  We are using BIRD 1.3.9. Can you confirm which version of bird
does not have this issues.


Question Is it only IPv4 problem only,

Yes it is an IPv4 problem,


or IPv6 as well?

Looking forward for your help pls.

Regards,
Ajai Kumar
