Example: Configuring Basic EVPN Active-Active Multihoming

 

This example shows how to configure an active-active multihomed customer edge (CE) devices and provider edge (PE) devices in an Ethernet VPN (EVPN).

Requirements

This example uses the following hardware and software components:

  • Four MX Series 5G Universal Routing Platforms with MPC interfaces only, where:

    • Two devices are configured as provider edge (PE) routers connected to a common multihomed customer site.

    • One device is configured as a remote PE router connected to a single-homed customer site.

    • One device is configured as a provider router.

  • • Two customer edge (CE) devices, where:

    • Two CE devices that are multihomed.

    • One CE devices that is single-homed .

Before you begin:

  1. Configure the router interfaces.

  2. Configure OSPF or any other IGP protocol.

  3. Configure a BGP internal group.

  4. Configure MPLS.

Overview

Figure 1 illustrates a simple EVPN topology. Routers PE1 and PE2 are provider edge (PE) routers connected to multihomed customer edge (CE) router CE1. Router P is the provider router connected to Routers PE1, PE2, and PE3. Router PE3 is connected to customer edge router CE2.
