Is IP CEF ECMP with include-port still happening in HW?
Would anyone from Cisco be able to confirm if IP CEF ECMP happens in hardware (on Cat9k and Cat3850) when include-port algortihm is configured?
ip cef load-sharing algorithm include-ports source
In my understanding this is critical for VXLAN deployments as ECMP is only effective if based on SOURCE UDP port, but even the latest IOS-XE configuration guides state the following:
**** The Layer 4 load-balancing algorithm applies to software switched packets. ****
For platforms that switch traffic using a hardware forwarding engine, the hardware load-balancing decision might be different from the software load-balancing decision for the same traffic stream. You might want to override the configured algorithm.
So, how do I read it? Does it mean that Layer 4 ECMP IS ALWAYS unconditionally applied to process switched; but command above is required to make sure hardware switched packets are also switched using Layer 4 ECMP? Or does it say that if I enable 'include-port' my algorithm becomes process switched? (I feel this is not right, but would rather confirm)
