Environment:
- A university has 2 campuses that are currently connected through a long-range point-to-point Wi-Fi bridge connection that provides a layer 2 bridge (both sites have the same subnet).
- However, the Wi-Fi connections throughput and reliability is limited (and affected by the weather), so the organization would like to connect the two buildings using additional connections.
Requirement:
- Throughput of the new connections need to be combined with the existing Wi-Fi connection.
- If the Wi-Fi connection fails, the router needs to be able to switch to other connections while maintaining session integrity.
- The same Layer 2 bridge with the same Subnet at both locations needs to be maintained.
Recommended Solution:
- Add a Balance 210 to both locations and plug the existing Layer 2 Bridge into the WAN1 on both devices. Note: In the diagram we have changed the wifi links to Layer 3 mode to provide WAN1 on each balance with a DHCP IP from the bridge device at each location. This is not a requirement, so long as the WAN1 ports of both Balance devices can route to each other over the wifi bridge (with statically assigned Ips for example).
- Install additional fixed line connectivity (or plug in a cellular dongle) to both locations and plug into the spare WAN ports.
- Setup a Layer 2 SpeedFusion VPN between the two peplink Balance Devices.
- Bandwidth of all connections is bonded into a single, high-bandwidth tunnel.
