[rbak-nsp] SE400 link aggregation problem with load balancing

[Elma K.]

Source IPs on SE400 side are from the pool configured on that device, and destination IPs are various (Internet traffic for our pppoe subscribers)...
Link IPs should not have meaning in this case, because link is just for transit traffic. Also, source and destination IPs should be different, because
it is the most unlikely that this traffic is from just one subscriber sending to just one IP...

Frans mean the source and destination IP of the packets traveling 
through the link. It does not have to be IP address of the link itself since the 
traffic can be transit traffic.

The link is with /30 mask, so I can not take just 1 higher IP... 
Maybe I can change both IPs on this link, 
but I have to check this with a 
coleague that works on the other device, to see if this is possible for 
him.

I will let You know when I get this info. In the meantime, if there 
is any other idea, I would appreciate it.

Hi 
Elma,

Do you by any change use the same IP address as destination and/or 
source?
The way the balancing works is based on something like source IP plus 
destination IP plus destination port, that will stick to the same physical 
link.
I ran into this problem once, solved the test by adding another source 
1 IP address higher and that took another link. 

I don’t know if you have 
the same kind of trouble there.

Kind 
regards,


Frans.

[rbak-nsp] SE400 link aggregation problem with load 
balancing

Hello.

I 
have SE400 connected to other device, and I have configured link aggregation on 
SE400, 
everything works fine except load-balancing from Redback's side... 

Traffic that is going from redback is not balanced on link group members, it 
is gong only on one port.

I guess there must be some configuration to 
change the way the device is doing this load balancing
between group 
members.

My device is with SEOS-2.6.7 (no chance for upgrade, 
unfortunately)
and the config is like this:

link-group hsiUplink-2PCh 
ether
 bind interface uplink-2 hsi

port ethernet 
1/5
 link-group hsiUplink-2PCh
!
port ethernet 
1/7
 link-group hsiUplink-2Ch
!
port ethernet 
3/12
 link-group hsiUplink-2PCh
!

Could anyone help me, 
please?

Best 
Regards.
Elma
