Очень похоже на это. Кажется, ты прав:
gateway#sh ip flow export
Flow export is enabled
Exporting flows to 213.59.238.11 (9991)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Exporting using source interface Loopback0
Version 5 flow records
3891 flows exported in 130 udp datagrams
0 flows failed due to lack of export packet
0 export packets were sent up to process level
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
0 export packets were dropped due to no fib
0 export packets were dropped due to adjacency issues
0 export packets were dropped due to fragmentation failures
0 export packets were dropped due to encapsulation fixup failures
gateway# clear ip flow stats
gateway#sh ip flow export
Flow export is enabled
Exporting flows to 213.59.238.25 (9991)

Но обе машины в одной сети, даже на физическом уровне. Что может
заставить пакеты на одну идти через fast switching, а на другую через
process switching?
