Today I faced a problem and I want to discuss it with you, I have 3 MLS switches ( SW1:3750, SW2:3550, SW3:3560 ) connected to each other by trunks. SW1 connected SW2 and SW2 connected to SW3. all Trunks allowed all VLANs and ( VTP version 2 , null VTP domain name all switches).
SW1 connected to PE router and SW2 & SW3 to customers.
Q1: which one should be VTP Server, and others to be transperant? best practice!!
Then I will tell you what happend with me.
