Networking Requirements

In Figure 1, we have implemented MLAG on SwitchA and SwitchB, the downstream SwitchC and SwitchD have dual-access to network through SwitchA and SwitchB respectively.

This topology uses MSTP to prevent link loops, VLAN 15 is mapped to MSTI-1 and VLAN 16 is mapped to MSTI-2. The entire topology belongs to only one MSTP domain named region1.
