If I understand VLANs are Layer 2 concept , and they are the Broadcast boundary, which means the Broadcast on one Vlan does not propagate to another VLAN. However I would like an Expert to clarify some dark areas about VLANs.
-- are VLANs the boundary of STP. I mean if there is a Switching Loop on one VLAN, the Loop will stay just on that VLAN and it does go to other VLANs ?
--If we have VLAN10 on a Switch in Building1 and 10 miles away in Building 2 we have another Switch that has VLAN10 and both VLANs are in the same VTP domain. is that considered Bad practice ?
--if we need to make Vlan2050 with 510 or 508 hosts has subnets 192.168.20.0 to 192.168.20.254 and 192.168.50.0 to 192.168.50.254 , to make it one VLAN for all wireless Access Points.
in other words, is it possible to have one VLAN for 2 subnets ?
