How to implement backup and restore in an enterprise
- Use is made of Cisco switch protected ports.
- The backup and restore VLANs are non-routed.
- Assign a supernet, e.g. 172.18.x.x /16 and subnet it down to /23 per VLAN. Bin (or nul route) these addresses on all firewalls and network choke points and core routers.
