netlab: Multi-Site VLANs
Imagine you want to create a simple multi-site network with netlab:
- The lab should have two sites (A and B).
- Each site has a layer-3 switch, a single VLAN (VLAN 100), and two hosts connected to that VLAN.
- As you don’t believe in the magic powers of stretched VLANs, you have a layer-3 (IPv4) link between sites.
