Re: FTP Transfer failure across 2 load-balanced links
Its indeed correct that the default CEF loadbalancing is per destination, however, from your describtion it seems the packet arives out of sequence at the destination which results in terminating FTP connection.
I would first ensure that Per packet loadbalancing is not in use. If the problem still exist, then following is a suggestion that would help you achieve what you are looking for:
1- Apply PBR for the FTP connection using the (verify-reachability) Object tracking to both nexthops (10.10.7.254 & 10.10.8.254).
2- This would ensure the FTP connection uses a single path but would be routed to the second path whenever the first path fails.
3- However, the above wont allow you to have FTP traffic loadbalance across equal paths but would ensure redundancy.
