Configuring MX Series Router Cloud CPE VRRP Services

This topic describes how to configure Virtual Router Redundancy Protocol (VRRP) with cCPE services.

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 for VRRP cCPE services:

  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 VRRP group. See Configuring a VRRP IPv4 Group for MX Series Router Cloud CPE Services.
  5. (Optional) Enable tracking of the CPE-facing Layer 2 interface. This step is optional if there is only one Layer 2 interface in the bridge domain. If the only Layer 2 interface is down, the bridge domain is down, including the IRB interface. This also brings down the VRRP instance. See Enabling Tracking of the CPE-Facing Layer 2 Interface.

Complete the following tasks to configure the secondary PE router for VRRP cCPE services:

  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 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.
