On a multilink bundle, all Q2 traffic (LFI traffic) from the multilink bundle is queued to Q2 of constituent links based on a hash computed from the source address, destination address, and IP protocol of the packet. If the IP payload is TCP or UDP traffic, the hash also includes the source port and destination port. As a result of this hash algorithm, all traffic belonging to one traffic flow is queued to Q2 of one constituent link.
