OSPF packets on an Etherchannel

Hi,

I am just asking me what is the behaviour of Etherchannel load balancing for OSPF packets (Hellos, LSAs etc..). The network is based on Catalyst 6500 running IOS and the Etherchannel load balancing method is src-dst IP address.

Which link is selected for OSPF multicast packets ? is there any load distribution over the available links ?

Thank you

Yves

Unless because the packets are locally sourced and treated differently, one would expect they would be hashed normally. I.e. use the same link of the channel if header is the same.

Thank you for your reply. Does this mean that all OSPF packets will use the same link as long no link failure occur ?

Thanks

I would think so, again, provided the values being hashed don't change. (I.e. same as any other packet.)
