Are you doing a 2-port etherchannel between the 920 and 3600 ?  Asking since you seem to be asking question about etherchannel load balancing and hashing


Are you doing 2 separate layer 3 subnets between the 920 and 3600 ?  asking since your subject heading implies so. (ospf equal cost LB)

...you might be confusing/mixing 2 different subjects and how-to's in the same explanation.

I think you mentioned the 920 is network side and 3600 is closer to customer... if so, please go to 920 and show a customer route on the 3600 that you wish you would load balance please... sanitize your output to protect the innocent...

Show ip route a.b.c.d

Show ip arp of next hop

If it goes via L2....

Show mac-address-table address aaaa.bbbb.cccc
