Configuring MX Series Router Cloud CPE VRRP with Ethernet OAM Services

This procedure sets up CFM monitoring for the access link between the PE router and the CPE. You can have multiple aggregation switches between the router and the CPE device. To perform the access link monitoring, you need to configure CFM MEPs in the PE router and CPE so that they can exchange heartbeat messages to monitor connectivity. Intermediate switches do not need a CFM-specific configuration, because the heartbeat messages are just regular Ethernet multicast packets.

Before you begin, make sure you have completed the steps for the cCPE common configuration. See Configuring the Common Configuration for MX Series Router Cloud CPE Services.

Then complete the following tasks to configure the primary PE router:

  1. Configure the subscriber access link. See Configuring the Subscriber Access Link.
  2. Configure the bridge domain. See Configuring the Bridge Domain for MX Series Router Cloud CPE Services.
  3. Configure the routing instance. See Configuring the VPN Routing Instance for MX Series Router Cloud CPE Services.
  4. Configure the first VRRP group. The virtual IP address for the VRRP group is the gateway address of the corresponding subnet in the cloud CPE LAN. See Configuring a VRRP IPv4 Group for MX Series Router Cloud CPE Services.
  5. Configure Ethernet OAM. See Configuring MX Series Router Cloud CPE Ethernet OAM for VRRP Services.

Complete the following tasks to configure the Layer 2 CPE.

Note:

This procedure uses a Juniper EX Series Ethernet Switch for the Layer 2 CPE.

  1. Configure the Layer 2 CPE. See Configuring the Layer 2 CPE When Running MX Series Router Cloud CPE Ethernet OAM for VRRP Services.

Complete the following tasks to configure the secondary PE router:

  1. Configure the subscriber access link. See Configuring the Subscriber Access Link.

  2. Configure the bridge domain. See Configuring the Bridge Domain for MX Series Router Cloud CPE Services.

  3. Configure the routing instance. See Configuring the VPN Routing Instance for MX Series Router Cloud CPE Services.

  4. Configure the first VRRP group. The virtual IP address for the VRRP group is the gateway address of the corresponding subnet in the cloud CPE LAN. See Configuring a VRRP IPv4 Group for MX Series Router Cloud CPE Services.

  5. Configure Ethernet OAM. See Configuring MX Series Router Cloud CPE Ethernet OAM for VRRP Services.
