Configuring MX Series Router Cloud CPE VRRP with DHCP Services

For customers who run VRRP between two cCPE instances to achieve dual access and who also want to use DHCP to allocate IP addresses for their devices, you can configure DHCP relay agents in the two cCPE instances and point to the same DHCP server.

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 tracking of the CPE facing Layer 2 interface for the first VRRP. See Enabling Tracking of the CPE-Facing Layer 2 Interface.
  6. Configure the DHCP relay agent. See Configuring MX Series Router Cloud CPE DHCP Relay Agent 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 tracking of the CPE-facing layer 2 interface for the first VRRP. See Enabling Tracking of the CPE-Facing Layer 2 Interface.

  6. Configure the DHCP relay agent. See Configuring MX Series Router Cloud CPE DHCP Relay Agent Services.
