VXLAN Configuration
This section describes how to configure VXLAN on devices, without any controller.
- Overview of VXLAN
VXLAN allows a virtual network to provide access services to a large number of tenants. In addition, tenants are able to plan their own virtual networks, not limited by the physical network IP addresses or broadcast domains. This greatly simplifies network management. - Licensing Requirements and Limitations for VXLAN
- Configuring VXLAN in Centralized Gateway Mode for Static Tunnel
Establishment
When VXLAN in centralized gateway mode for static tunnel establishment is deployed, traffic across network segments is forwarded through Layer 3 VXLAN gateways to implement centralized traffic management. - Configuring VXLAN in Centralized Gateway Mode Using BGP EVPN
When VXLAN in centralized gateway mode using BGP EVPN is deployed, traffic across network segments is forwarded through Layer 3 VXLAN gateways to implement centralized traffic management. - Configuring VXLAN in Distributed Gateway Mode Using BGP EVPN
Distributed VXLAN gateways can be configured to address problems that occur in legacy centralized VXLAN gateway networking, for example, forwarding paths are not optimal, and the ARP entry specification is a bottleneck on Layer 3 gateways. - Configuring Three-Segment VXLAN to Implement DCI
Three-Segment VXLAN can be configured to enable communication between VMs in different DCs. - Configuring the Static VXLAN Active-Active Scenario
In the scenario where a data center is interconnected with an enterprise site, a CE is dual-homed to a VXLAN network. In this way, carriers can enhance VXLAN access reliability to improve the stability of user services so that rapid convergence can be implemented in case of a fault. - Configuring the Dynamic VXLAN Active-Active Scenario
In the scenario where a data center is interconnected with an enterprise site, a CE is dual-homed to a VXLAN network. In this way, carriers can enhance VXLAN access reliability to improve the stability of user services so that rapid convergence can be implemented in case of a fault. - Configuring BRAS Access Through a PW and a VXLAN Tunnel
As virtual networks develop, if device resources become insufficient for processing access user traffic, traffic can be load balanced to virtual BRASs in data centers. Specifically, a device can establish a VXLAN tunnel with a virtual BRAS for user access. - Maintaining VXLAN
This section describes how to clear VXLAN statistics and monitor the VXLAN running status. - Configuration Examples for VXLAN
This section describes the typical application scenarios of VXLANs, including networking requirements, configuration roadmap, and data preparation, and provides related configuration files.
