Configuring a Layer 3 VXLAN Gateway

This section describes how to configure a Layer 3 VXLAN gateway. To allow VMs on different network segments to communicate, a Layer 3 VXLAN gateway must be deployed, and the default gateway address of the VMs must be the IP address of the BDIF interface of the Layer 3 gateway.

Procedure

Run system-view
The system view is displayed.
Run interface vbdif bd-id
A BDIF interface is created, and the BDIF interface view is displayed.

The BD ID specified must exist.
Configure an IP address for the VBDIF interface to implement Layer 3 interworking.
- On IPv4 overlay networks, run ip address ip-address { mask | mask-length } [ sub ].
  
  An IPv4 address is configured for the VBDIF interface.
- On IPv6 overlay networks, perform the following operations:
  1. Run ipv6 enable
    
    IPv6 is enabled for the VBDIF interface.
  2. Run ipv6 address { ipv6-address prefix-length | ipv6-address/prefix-length }
    
    Or, ipv6 address { ipv6-address prefix-length | ipv6-address/prefix-length } eui-64
    
    A global unicast address is configured for the VBDIF interface.
(Option) Run mac-address mac-address
An MAC address is configured for the BDIF interface.
(Option) Run bandwidth bandwidth
The bandwidth is configured for the VBDIF interface.
Run commit
The configuration is committed.
