Nexus N3K VLAN Issue

[John N]

Hello dears,

I have a question, Can I create over 1000 VLANs on nexus while using RSTP mode?

I tried but it denied me, but when I use MSTP it allow me to configure, the nexus are connected to many 2960 Catalyst switches and all 2960 are using RSTP, when I use MSTP in Nexus some of 2960 are going to blocking state, and Nexus connect to MikroTik Router I can see the mac addresses in MikroTik but I can see in neighbors of Nexus

thanks for your help
