I have a network with L2 switches and a L3 switch connected directly to the ISP router. If I want to add another L3 switch though how would I set it up? Since the current L3 switch is doing the vlan routing and routing all the traffic to the router for internet access, what role does the second L3 play?
1. Will the vlan interfaces I created on the current L3 switch come over by its self, vtp possibly, or do I have to manually recreate them? Is it even possible to create the interface vlan xx's since they may even have ip conflicts?
2. If it is possible to add this switch, then which L3 switch will do the routing for the vlans, both? Which will be the L3 that routes to the ISP router? Does one of them have to be setup as a downstream L3 switch?
This and any other information that i need to know on how to add this switch please let me know.
