[c-nsp] Etherchannel load balancing

[Ivan Šimko]

Hi all

I've got two switches 3560
group with 2xFE on both switches and inteconnected together.
port channel is L2
2 VRFs - ivan, mark
4 VLANs:
- vlan 100 VRF "ivan" for interconnection between swtiches
- vlan 11 VRF "ivan" for customer's connection

- vlan 200 VRF"mark" for interconnection between switches
- vlan 12 VRF "mark" for customer's connection

ports 12 and 13 as trunks
- interconnection between switches

OSPF runs over SVIs of 100 and 200.

I'm strugling with load balancing:
when I setup port channel load balancing dst-ip switch does correct
balancing between interconnected vlans but not for customers' vlans.
- vlan 100 would use port 12 - switch interconnection
- vlan 200 would use port 13 - switch interconnection
- vlan 11 would use port 13 - customer 1
- vlan 12 would use port 13 - customer 2

when I setup port channel load balancing src-dst-ip switch does correct
balance for customers' vlans but not for interconnected vlans.
- vlan 100 would use port 13
- vlan 200 would use port 13
- vlan 11 would use port 12
- vlan 12 would use port 13

Result is not full bandwidth used for both customers' traffic resp. only 100
Mbps.


Any ideas how to sort it out?

thanks
