BGP Big Chunk Pool

Customer told me that all router in his network notify this msg "Mar 5 07:45:20.840 BKK: %BGP-6-BIGCHUNK: Big chunk pool request (268) for community. Replenishing with malloc" .

So, Is anybody know what kind of community in bgp make router notify this msg?

My customer network is Internation Internet Gateway.


Re: BGP Big Chunk Pool


A large chunk pool has been requested. If the static chunk pools size cannot service the request, it will be serviced with a memory allocation (malloc).
