Layer 3 Link Load Balancing

10/27/2011 By Andrew Roderos Leave a Comment

CCDP ARCH book states to avoid CEF (Cisco Express Forwarding) polarization, the recommended way to do is to use alternating input hashes in the core and distribution layer. In the core, use the default hash, which is based on only Layer 3 information. In the distribution layer, use Layer 3 and 4 information as the input into the CEF hash algorithm.

To enable Layer 3 and 4 CEF hashing algorithm, issue this command:

Switch (config)# mls ip cef load-sharing full
