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).
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:
Configure the router interfaces.
Configure OSPF or any other IGP protocol.
Configure a BGP internal group.
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.
CLI Quick Configuration
The configurations parameters for the routers are as follows:
