hi! I've a setup similar to the diagram in the file attached.
my core switch has it own vtp domain and vlan 210 (transit vlan) is part of the vtp domain abc in the core sw. I've another switch on the production network which is configured with vlan45 (not part of the abc vtp domain). I'm not too sure what's the setup of the firewall. Currently i can ping host on the production network. I've a static route from my core switch to the production network.
My questions are,
1) why do i need a "transit vlan" here?
2) Can i create vlan 45 in vtp abc and use that vlan/network segment in the core sw?
3) Through the firewall, can i use vlan 45 in my corporate network which is in the core sw?
One question which might not related to the questions above. Within a sw itself can i create a vtp domain, and have another vlan created within that switch and not joining that particular vlan into the vtp domain? or can i have multiple vtp domain within a switch itself?
