Introduction
This document provides configuration examples for using Distributed Resilient Network Interconnect (DRNI) on an Ethernet Virtual Private Network (EVPN) network.
DRNI virtualizes two physical devices into one system through multichassis link aggregation. You can use DRNI to virtualize two VTEPs or EVPN gateways into one distributed-relay (DR) system to avoid single points of failure.
Prerequisites
The configuration examples were created and verified in a lab environment, and all the devices were started with the factory default configuration. When you are working on a live network, make sure you understand the potential impact of every command on your network.
The following information is provided based on the assumption that you have basic knowledge of DRNI and EVPN.
General restrictions and guidelines
Before you can configure EVPN, you must perform the following tasks:
1. Set the system operating mode to standard by using the system-working-mode standard command.
2. Save the configuration.
3. Reboot the device.
If you enable Layer 3 forwarding for VXLANs, reserve one global-type VLAN interface resource for the VSI interface of each VXLAN before the VXLAN is created on the following hardware:
· The S12500X-AF F card series.
· The S12500-X switch series.
· The S9800 switch series.
You do not need to reserve VLAN interface resources for the S12500X-AF H card series.
Example: Configuring DRNI using an Ethernet aggregate link as the IPL on EVPN VTEPs
Network configuration
As shown in Figure 1, perform the following tasks to make sure the VMs can communicate with one another:
· Configure VXLAN 10 on Switch A, Switch B, and Switch D.
· Configure DRNI on Switch A and Switch B to virtualize them into one VTEP. Configure an Ethernet aggregate link as the IPL between the switches.
· Configure Switch C as a route reflector (RR).
Analysis
To conserve resources, configure Switch C to reflect routes for Switch A, Switch B, and Switch D.
Software versions used
Table 1 shows the software versions used in this configuration example.

Restrictions and guidelines
In a DR system, DR member devices must have the same EVPN configuration.
Make sure the outer VLAN IDs configured on Ethernet service instances of different VSIs do not overlap. The Ethernet service interfaces that match the same outer VLAN ID on different ports must be mapped to the same VSI.
For EVPN to run correctly on a DR system, you must execute the undo mac-address static source-check enable command on IPPs and IRF physical interfaces of the DR member devices.
As a best practice, use the IP address of a loopback interface as the virtual VTEP address.
By default, interfaces on the device are disabled (in ADM or Administratively Down state). To have an interface operate, you must use the undo shutdown command to enable that interface.

Example: Configuring DRNI using a VXLAN tunnel as the IPL on EVPN VTEPs
Network configuration
As shown in Figure 2, perform the following tasks to make sure the VMs can communicate with one another:
· Configure VXLAN 10 on Switch A, Switch B, and Switch D.
· Configure DRNI on Switch A and Switch B to virtualize them into one VTEP. Manually set up a VXLAN tunnel as the IPL between the switches.
· Configure Switch C as an RR.
Analysis
To make sure the overlay network has connectivity,, configure a routing protocol on these switches to advertise routes for reaching their interfaces, including the loopback interfaces. In this example, OSPF is used.
To conserve resources, configure Switch C to reflect routes for Switch A, Switch B, and Switch D.
Software versions used
Table 2 shows the software versions used in this configuration example.

Restrictions and guidelines
In a DR system, DR member devices must have the same EVPN configuration.
As a best practice, use the IP address of a loopback interface as the virtual VTEP address.
You can configure only the following criteria for Ethernet service instances on DR interfaces:
· encapsulation s-vid { vlan-id | vlan-id-list }
· encapsulation untagged
As a best practice, do not redistribute external routes on the DR member devices.
You must disable spanning tree on the Layer 2 traffic outgoing interface for the VXLAN tunnel that acts as the IPL.
By default, interfaces on the device are disabled (in ADM or Administratively Down state). To have an interface operate, you must use the undo shutdown command to enable that interface.

Example: Configuring DRNI using an Ethernet aggregate link as the IPL on EVPN gateways
Network configuration
As shown in Figure 3, perform the following tasks to make sure the VMs can communicate with one another:
· Configure VXLAN 10 on Switch A, Switch B, and Switch D, and configure VXLAN 20 on Switch A and Switch B.
· Configure Switch A, Switch B, and Switch D as distributed EVPN gateways to provide Layer 3 forwarding service for VMs.
· Configure DRNI on Switch A and Switch B to virtualize them into one VTEP. Configure an Ethernet aggregate link as the IPL between the switches.
· Configure Switch C as an RR.
Analysis
To make sure the overlay network has connectivity,, configure a routing protocol on these switches to advertise routes for reaching their interfaces, including the loopback interfaces. In this example, OSPF is used.
To conserve resources, configure Switch C to reflect routes for Switch A, Switch B, and Switch D.
Software versions used
Table 3 shows the software versions used in this configuration example.

Restrictions and guidelines
In a DR system, DR member devices must have the same EVPN configuration.
Make sure the outer VLAN IDs configured on Ethernet service instances of different VSIs do not overlap. The Ethernet service interfaces that match the same outer VLAN ID on different ports must be mapped to the same VSI.
For EVPN to run correctly on a DR system, you must execute the undo mac-address static source-check enable command on IPPs and IRF physical interfaces of the DR member devices.
As a best practice, use the IP address of a loopback interface as the virtual VTEP address.
By default, interfaces on the device are disabled (in ADM or Administratively Down state). To have an interface operate, you must use the undo shutdown command to enable that interface.

Example: Configuring DRNI using a VXLAN tunnel as the IPL on EVPN gateways
Network configuration
As shown in Figure 4, perform the following tasks to make sure the VMs can communicate with one another:
· Configure VXLAN 10 on Switch A, Switch B, and Switch D, and configure VXLAN 20 on Switch A, and Switch B.
· Configure Switch A, Switch B, and Switch D as distributed EVPN gateways to provide Layer 3 forwarding service for VMs.
· Configure DRNI on Switch A and Switch B to virtualize them into one VTEP. Manually set up a VXLAN tunnel as the IPL between the switches.
· Configure Switch C as an RR.
Analysis
To make sure the overlay network has connectivity,, configure a routing protocol on these switches to advertise routes for reaching their interfaces, including the loopback interfaces. In this example, OSPF is used.
To conserve resources, configure Switch C to reflect routes for Switch A, Switch B, and Switch D.
Software versions used
Table 4 shows the software versions used in this configuration example.

Restrictions and guidelines
In a DR system, DR member devices must have the same EVPN configuration.
As a best practice, use the IP address of a loopback interface as the virtual VTEP address.
You can configure only the following criteria for Ethernet service instances on DR interfaces:
· encapsulation s-vid { vlan-id | vlan-id-list }
· encapsulation untagged
As a best practice, do not redistribute external routes on the DR member devices.
You must disable spanning tree on the Layer 2 traffic outgoing interface for the VXLAN tunnel that acts as the IPL.
By default, interfaces on the device are disabled (in ADM or Administratively Down state). To have an interface operate, you must use the undo shutdown command to enable that interface.
