I have what is probably a super simple switching question, but can't seem to find a clear answer. I'm a routing guy who does BGP and MPLS for a living, but am stumped my this switching problem:
I have two switches with many VLans and a VTP domain. I want to connect my two switches to a group of 4 untrusted switches, have one common L3 vlan between my 2 switches and their 4 switches, and have spanning tree be fully functional throughout to provide L2 redundancy..
If I hand off to them as access ports in the one VLAN I want, will spanning tree still function????
OR, If I had off to them as trunk ports and prune all VLANs except the one VLAN I want to talk to them on (and VLAN 1 which I cant prunt), how do I secure my VTP domain so they cant become a VTP server and kill my VTP domain????
Any help would be extremely appreciated.. Thanks much!
