Configuration Notes of Routed Interface

Pay attention to the following precautions before configuring the routed interfaces:

• Routed interface and sub-interface are supported in VXLAN underlay configuration, but not in VXLAN overlay configuration. In VXLAN underlay configuration, if the outgoing interface of a VXLAN tunnel is a sub-interface, then the VLAN of this sub-interface is not allowed to be assigned to other interfaces.
• If a VLAN has already been configured in other layer 3 functions, such as been assigned to a sub-interface, then it cannot be used for layer 2 functions, for example, it cannot be assigned to other interfaces, or be used in other layer 2 functions, such as PVLAN.
