Currently I'm planning to implement ether-channels on 7600 routers, but there's something that's still not clear to me, regarding the load balancing behavior, for L2VPN and L3VPN.
I've read that 7600 in MPLS default load balance behavior is to take the SIP and DIP if present and the bottom of the stack label or the 5th label depending upon the number of labels on the stack. In l2VPN scenarios when ether-channel is used, if no IP traffic is present what is the default behavior of the etherchannel to calculate the load balancing hash function to select a given link on the bundle.
