[j-nsp] AE Bundle Load Balancing | EX series

[Ramesh]

Hi Bill

>From "JUNOS Enterprise Switching" book (page 629) -

"Load balancing over AE
When sending traffic over multiple member links, the draft specifies that
traffic that is
part of the same “conversation” should always be on the same link. This is
done by
creating a hash, based on the conversation and specifying that every packet
with that
hash takes the same link. The exact details of the conversation are not
defined, but in
JUNOS the hashing works as follows:
 • Non-IP traffic hashes on the source and destination MAC addresses (SMAC
and
    DMAC).
 • IP traffic uses the SMAC and DMAC addresses and the IP address, and, if
Layer 4
    is present, port numbers.
These flows are not user-configurable at this time.
               The hash is used only for transit traffic over the AE link.
CPU control
               packets are always sent out on the lowest-numbered link.
"

Hope this helps.

Regards,
Ramesh
