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 the device is a VTEP, enable Layer 2 or Layer 3 forwarding for VXLANs. If the device is an EVPN gateway, enable Layer 3 forwarding for VXLANs.

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).

Figure 1 Network diagram

 

Analysis

To make sure the overlay network has connectivity, configure a routing protocol on the 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

This configuration example was created and verified on S6890 CMW710-R2712.

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 S6890 switches 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.

Figure 2 Network diagram

 

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

This configuration example was created and verified on S6890 CMW710-R2712.

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 S6890 switches 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.

Figure 3 Network diagram

 

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

This configuration example was created and verified on S6890 CMW710-R2712.

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 S6890 switches 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.

Figure 4 Network diagram

 

 

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

This configuration example was created and verified on S6890 CMW710-R2712.

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 S6890 switches are disabled (in ADM or Administratively Down state). To have an interface operate, you must use the undo shutdown command to enable that interface.
