Hi David, There is no CPU hit associated with the hash-key statements on M/T-series. In fact hardware always uses hashing when load balancing is enabled by "load-balance per-packet" policy action. Hash-key stanza gives you choice of data that is used by hash function. When no hash-key statement configured only Layer 3 header contents is used by default. Sometimes you notice unequal load distribution pattern for some kinds of traffic then you are encouraged to tune data selection for hash-key. There is no performance hit as far as I know. http://www.juniper.net/techpubs/software/junos/junos82/swconfig82-policy/html/policy-actions-config11.html -Alexander _______________________________________________ juniper-nsp mailing list juniper-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/juniper-nsp
