I would like to know if a Arista switch uses DMA (Direct memory access) to copy a control packet (e.g OSPF) or a packet for which there is no entry in FIB to CPU? If not how does it happen?
I’m not familiar with the internal architecture/ packet path (ASIC cpu), so any good reference docs on the same would be helpful too.
