Let's say a virtual stack is currently setup with L3 routing enabled and several defined VLANs. One of those VLANs is 104.
Now, you connect a new flexible stack to the existing virtual stack. You are a glutten for punishment and need to enable L3 routing on the new flexible stack.
Do you have to create the same VLAN (say 2500 for this example) on each stack (with different interface IPs) as a transit link between the two stacks?
Existing virtual stack: VLAN 2500, 192.168.10.0/24, interface 192.168.10.1
New flexible stack: VLAN 2500, 192.168.10.0/24, interface 192.168.10.2, (what would the default gateway be for the first time L3 routing setup?
VLAN 104 was already setup on the existing virtual stack. Do you need to "recreate" it on the new stack if you will be using it on the new flexible stack or no?
