Hello Igor,
While filtering VLANs is most simple way to distribute load,
you should remember, that it provides no backup in case of link
failure.
You should also consider this options
1) Using Etherchannel
2) Using spanning-tree vlan xx port-priority command so that different
VLAN's STPs would select different root ports.
Here is supporting link for second option:
