EtherChannel load balancing
Having trouble wrapping my brain around etherchannel traffic distribution.
When using src-dst-ip a Cisco white paper calculates the following:
test etherchannel load-balance int port-channel 1 ip 1.1.1.1 2.2.2.2
Computed RBH: 0x5
The CCNP OCG leads me to believe I should use the last octet and end up with the following:
001 - 1.1.1.1
010 - 2.2.2.2
011 - XOR
2 interfaces - XOR value of 1 - Interface 1 is selected
4 interfaces - XOR value of 3 - Interface 3 is selected
8 interfaces - XOR value of 3 - Interface 3 is selected
Is calculated XOR not the equivalent to RBH? What am I missing? It's my first day using etherchannel, please be gentle

The first link you posted is basically what the OCG details. The second link you posted is actually the one that originally confused me after learning from the OCG. This line:
6500-20-sp#test etherchannel load-balance int port-channel 1 ip 1.1.1.1 2.2.2.2
Computed RBH: 0x5
I thought the decimal value of 3 I calculated was the 'RBH'. But that paper listed a different result.2014 Certification Goals: 70-410 [ ] CCNA:S [ ] Linux+ [ ]
