Introduction

This document provides EVPN multicast configuration examples.

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 EVPN and multicast.

General restrictions and guidelines

On the S12500GAF series switches, only SF interface modules support EVPN multicast.

Example: Configuring Layer 2 EVPN multicast

Network configuration

As shown in Figure 1, configure Layer 2 EVPN multicast as follows:

·     Configure Leaf 1 and Leaf 2 as distributed EVPN gateways. Assign the multicast receivers attached to Leaf 1 and the multicast source attached to Leaf 2 to VXLAN 10.

·     Configure Leaf 1, Leaf 2, and the RR to set up BGP EVPN peer relationships in AS 65000 of the overlay network. Configure the RR to reflect BGP EVPN routes between Leaf 1 and Leaf 2.

·     Configure OSPF on Leaf 1, Leaf 2, and the RR for them to have Layer 3 connectivity on the underlay network.

Figure 1 Network diagram

 

Analysis

To enable Layer 2 multicast forwarding in the EVPN network, perform the following tasks:

·     Enable IGMP snooping on the leaf devices for them to snoop the IGMP membership reports sent by the multicast receivers.

·     For the leaf devices to create Layer 2 multicast forwarding entries, configure the leaf devices to advertise multicast group join requests through selective multicast Ethernet tag (SMET) routes.

Applicable hardware and software versions

The following matrix shows the hardware and software versions to which this configuration example is applicable:

 

Hardware	Software version
S12500G-AF	Release 8053P05 and later
S12500CR	Release 8053P05 and later
S10500X-G	Release 7753P05 and later
S7500X-G	Release 7753P05 and later

 

Restrictions and guidelines

IGMP snooping restrictions and guideline

IGMP snooping configuration in a VSI takes effect only on the member ports in the VSI.

In an EVPN VXLAN network, the IGMP snooping querier in a VSI does not include VLAN tags in IGMP general queries. As a best practice, do not enable the IGMP snooping querier in a VSI if the VSI uses the Ethernet access mode.

The interface where an Ethernet service instance resides must allow the VLANs that the Ethernet service instance matches.

Distributed EVPN gateway restrictions and guideline

When you configure VSI interfaces on distributed EVPN gateways, follow these restrictions and guidelines:

·     Do not assign reserved MAC addresses to VSI interfaces.

·     You must assign the same MAC address to the VSI interfaces with L3 VXLAN IDs associated

·     If you use the mac-address command to modify the MAC address of a L3 VXLAN ID associated VSI interface on a DR system, also modify the MAC address of the other L3 VXLAN ID associated VSI interfaces. These VSI interfaces must use the same MAC address.

·     If a distributed EVPN gateway is connected to an IPv6 site, make sure the VSI interfaces with L3 VXLAN IDs associated use the same link-local address.

·     On different distributed EVPN gateways, the VSI interface of a VXLAN must use the same IP address and MAC address to provide services.

·     The L3 VXLAN ID of a VSI interface cannot be the same as the VXLAN ID specified by using the mapping vni command.

·     As a best practice, do not use ARP flood suppression and local proxy ARP or ND flood suppression and local ND proxy together on distributed EVPN gateways. If both ARP flood suppression and local proxy ARP are enabled on a distributed EVPN gateway, only local proxy ARP takes effect. If both ND flood suppression and local ND proxy are enabled on a distributed EVPN gateway, only local ND proxy takes effect.
