Example for Configuring BD EVPN IRB over SR-MPLS TE

This section provides an example for configuring BD EVPN IRB over SR-MPLS TE.

Networking Requirements

On the network shown in Figure 1, the EVPN and VPN functions are configured to transmit Layer 2 and Layer 3 traffic to allow communication between different sites on the backbone network. If Site 1 and Site 2 are connected through the same subnet, create an EVPN instance on each PE to store EVPN routes. Layer 2 forwarding is based on an EVPN route that matches a MAC address. If Site 1 and Site 2 are connected through different subnets, create a VPN instance on each PE to store VPN routes. In this situation, Layer 2 traffic is terminated, and Layer 3 traffic is forwarded through a Layer 3 gateway. In this example, PEs transmit service traffic over SR-MPLS TE tunnels.

Figure 1 Networking of BD EVPN IRB over SR-MPLS TE

Interface 1, interface 2, and sub-interface 1.1 in this example represent GE 0/1/0, GE 0/1/8, and GE 0/1/0.1, respectively.


Configuration Notes

When configuring BD EVPN IRB over SR-MPLS TE, note the following:

  • On 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, and 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 a PE as the EVPN source address is recommended.

Configuration Roadmap

The configuration roadmap is as follows:

  1. Configure an IGP to allow communication between PE1, PE2, and P.

  2. Configure an SR-MPLS TE tunnel on the backbone network.

  3. Configure an EVPN instance and a VPN instance on each PE.

  4. Configure an EVPN source address on each PE.

  5. Configure the Layer 2 Ethernet sub-interfaces connecting PEs and CEs.

  6. Configure a vBDIF interface on each PE and bind the vBDIF interface to a VPN instance.

  7. Configure and apply a tunnel policy so that EVPN can recurse to SR-MPLS TE tunnels.

  8. Establish BGP EVPN peer relationships between PEs.

  9. Configure CEs to communicate with PEs.

Data Preparation

To complete the configuration, you need the following data:

  • EVPN instance name (evrf1) and VPN instance name (vpn1)

  • EVPN instance evrf1's RD (100:1) and RT (1:1) on PE1, EVPN instance evrf1's RD (200:1) and RT (1:1) on PE2, VPN instance vpn1's RD (100:2) and RT (2:2) on PE1, and VPN instance vpn1's RD (200:2) and RT (2:2) on PE2

Procedure

  1. Configure IP addresses for the interfaces connecting PEs and P2 according to Figure 1.

  2. Configure an IGP to allow communication between PE1, PE2, and P. IS-IS is used as an IGP protocol in this example.

[*PE2] commit

    After completing the configuration, run the display isis peer command to check that the status of the IS-IS neighbor relationship between PE1, PE2, and P is Up. Run the display ip routing-table command to view that the PEs have learned the routes to Loopback1 of each other.

    The following example uses the command output on PE1.

  7. Configure a vBDIF interface on each PE and bind the vBDIF interface to a VPN instance.

    # Configure PE1.

    [~PE1] interface Vbdif10

  8. Configure and apply a tunnel policy so that EVPN can recurse to SR-MPLS TE tunnels.

    # Configure PE1.

  9. Establish BGP EVPN peer relationships between PEs.

    # Configure PE1.

    [~PE1] bgp 100
[*PE1-bgp] peer 3.3.3.3 as-number 100
[*PE1-bgp] peer 3.3.3.3 connect-interface loopback 1

[*PE2] commit

    After completing the configuration, run the display bgp evpn peer command to check that BGP peer relationships have been established between PEs and are in the Established state. The following example uses the command output on PE1.

    [~PE1] display bgp evpn peer
 
 BGP local router ID : 1.1.1.1
 Local AS number : 100
 Total number of peers : 1                 Peers in established state : 1

  10. Configure CEs to communicate with PEs.

    # Configure CE1.

    [~CE1] interface GigabitEthernet 0/1/0.1 mode l2
[*CE1-GigabitEthernet0/1/0.1] encapsulation dot1q vid 10
[*CE1-GigabitEthernet0/1/0.1] rewrite pop single

[*CE2-GigabitEthernet0/1/0.1] rewrite pop single
[*CE2-GigabitEthernet0/1/0.1] quit
[*CE2] commit

  11. Verify the configuration.

    After completing the configurations, run the display bgp evpn all routing-table command on PEs to view the EVPN routes sent from the peer PEs. The following example uses the command output on PE1.

    [~PE1] display bgp evpn all routing-table
