Hi, Here is the topology. Pls let me know if missing anything. Thanks.
sw1 (f0/13-15) -- trunk - sw2(f0/13-15) sw1 (f0/16-18) -- trunk - sw3 (f0/13-15) sw1 (f0/19-21) -- trunk - sw4 (f13-15) sw2 is server sw3 and sw4 are clients sw1 made vtp mode transparent 1. create vlan X on sw2 2. it should go to sw1 (transparent) not learn but fwd them to sw3 and sw4 Issue: sw3 and sw4 are not learning vlan X. Trunks are formed. Domain name is matched. Enabled debugs but clients are not updating vtp database from server.
