Nexus 93128TX solution for Microsoft NLB

[deanaa]

Will be moving from Catalyst 6500 series to Nexus 9300 series switch and need to configure (Microsoft) NLB multicast on a Nexus 93128TX.  I read that NLB is not supported on the 9300 series but there are some workarounds.  The only solution I have found is to map a unicast IP address to a multicast MAC address and enabling MAC-based L2 lookups.  Are there any other recommendations for accomplishing this?

I found this document for doing it on a Nexus 7000, perhaps it will be similar.

Hello ,

Unfortunately, As far as I am aware there is no workaround at this point in time. This deployment method of NLB is not supported on the Nexus 9000 platform as documented in the NX-OS release notes.

You could reconfigure the NLB cluster to unicast mode as per the documentation Unicast NLB in N9k and follow the advice in https://tools.cisco.com/bugsearch/bug/CSCuq03168/ for a better outcome.

Hope it Helps..
