I solved this issue little differently after spending few hours debugging the issue. Issue:  ASDM throwing "asdm file transfer 500 http response" while doing a file transfer(asa firmware only) or upgrading the image. Summary: I was on 9.0.4 and was trying to upgrade to 9.1.6.  It had throwed the error multiple times despite of the system reboot and enough disk room. Later while i was going through the release notes, i figured i can not upgrade straight from 9.0.4 to 9.1.6 and i have to follow the upgrade path. Then i upgraded to 9.1.2 and then to 9.1.6. This has resolved the underlying "500" http response issue. So the issue was with the upgrade path in my case and i would suggest it is worth checking(release notes) this as a first step... Root Cause: upgrade path was the the root cause. Recommendation to Cisco: Error handling by ASDM in this case was not quite relevant. It should have throw a proper text message  along with http response code. ... View more

  Hello There i was also looking for suggestions on the similar concept. I was trying to choose prefixes from only one neighbor and redist them to EIGRP. I could successfully simulate that and it is just working as i need. note:  Naming convention used here according to my convenience.    Config: ISP Router: -------------- Building configuration...
