Example for Configuring EVPN E-LAN over mLDP P2MP Tunnels

On a network where an EVPN carries multicast services, to reduce redundant traffic and conserve bandwidth resources, configure an EVPN E-LAN over mLDP P2MP tunnel for service transmission.

Networking Requirements

On the network shown in Figure 1, EVPN is configured on the PEs and used to carry multicast services. PE1 is the root node, and PE2 and PE3 are leaf nodes. The access side is the multicast source and the receiver. By default, an EVPN sends multicast service traffic from PE1 to PE2 and PE3 by means of ingress replication. Specifically, PE1 replicates a multicast packet into two copies and sends them to the P functioning as an RR. The P then sends one copy to PE2 and the other copy to PE3. For each additional receiver, an additional copy of the multicast packet is sent. This increases the volume of traffic on the link between PE1 and the P, consuming bandwidth resources. To conserve bandwidth resources, you can configure EVPN to use an mLDP P2MP tunnel to transmit multicast services. After the configuration is complete, PE1 sends only one copy of multicast traffic to the P. The P replicates the multicast traffic into copies and sends them to the leaf nodes, reducing the volume of traffic between PE1 and P.

Figure 1 Configuring EVPN E-LAN over mLDP P2MP tunnels

Interfaces 1 through 3 in this example represent GE 0/1/0, GE 0/1/8, and GE 0/1/16, respectively.


Precautions

When you configure EVPN to use an mLDP P2MP tunnel for service transmission, note the following:

  • For the same EVPN instance, the export VPN target list of a site shares VPN targets with the import VPN target lists of the other sites. Conversely, the import VPN target list of a site shares VPN targets with the export VPN target lists of the other sites.

  • Using the local loopback interface address of each PE as the source address is recommended.

Configuration Roadmap

The configuration roadmap is as follows:

  1. Configure an IGP on the backbone network to allow PEs and the RR to communicate.

  2. Configure MPLS and mLDP P2MP both globally and per interface on each node of the backbone network.

  3. Create an EVPN instance in BD mode and a BD on each PE, and bind the BD to the EVPN instance on each PE.

  4. Configure a source address on each PE.

  5. Configure each PE's sub-interface connecting to a CE.

  6. Configure an ESI for each PE interface that connects to a CE.

  7. Configure BGP EVPN peer relationships between the PEs and RR, and configure the PEs as RR clients.

  8. Configure EVPN to use an mLDP P2MP tunnel for service transmission on each PE.

Data Preparation

To complete the configuration, you need the following data:

  • EVPN instance name: evrf1

  • EVPN instance evrf1's RD (100:1) and RT (1:1) on each PE

Procedure

  1. Assign an IP address to each interface on the RR and PEs according to Figure 1. For configuration details, see Configuration Files in this section.
  2. Configure an IGP on the backbone network to allow PEs and the RR to communicate. OSPF is used in this example.

    After the configurations are complete, run the display bgp evpn peer command on the RR. The command output shows information about BGP peer relationships. In the following example, the output shows that BGP peer relationships are established between the PEs and RR and that they are in the Established state.

[*PE3] commit

  10. Verify the configuration.

    Run the display evpn vpn-instance name evrf1 inclusive-provider-tunnel verbose command on PE1. The command output shows information related to the root node.

    [~PE1] display evpn vpn-instance name evrf1 inclusive-provider-tunnel verbose
 VPN-Instance Name and ID : evrf1, 3
  Address family bd-evpn
  Route Distinguisher : 100:1

  Export VPN Targets  : 1:1
  Import VPN Targets  : 1:1
  Bridge-domain       : 10

    Root ip        : 1.1.1.1
    Opaque value   : 01000400008001
    State          : up
  Egress provider tunnel
  Egress PMSI count: 0

    Run the display evpn vpn-instance name evrf1 inclusive-provider-tunnel verbose command on PE2 or PE3. The command output shows information related to the leaf node. The following example uses the command output on PE2:

    [~PE2] display evpn vpn-instance name evrf1 inclusive-provider-tunnel verbose
 VPN-Instance Name and ID : evrf1, 3

  Export VPN Targets  : 1:1
  Import VPN Targets  : 1:1
  Bridge-domain       : 10
  Ingress provider tunnel
  Egress provider tunnel
  Egress PMSI count: 1
   *PMSI type      : P2MP mLDP
