I have this scenario. I have the alarm system on vlan10 with 10.10.10.100/24 subnet. Below is the snapshot of my network:
MPLS<-->Core switch2<-->access switch1<--alarm system.
The alarm system doesn't need to be routed within my internal network. switch1 has DG as 10.10.200.1 (vlan200). my core is a layer 3 switch has SVI 200 with 10.10.200.1.
What is the DG for my alarm system?
