    Configuring the Control Node

    An important task after a successful installation is to configure the control node. This procedure shows how to configure basic BGP peering between one or more virtual network controller control nodes and any external BGP speakers. External BGP speakers, such as Juniper Networks MX80 routers, are needed for connectivity to instances on the virtual network from an external infrastructure or a public network.

    Before you begin, ensure that the following tasks are completed:

    • The Contrail Controller base system image has been installed on all servers.
    • The role-based services have been assigned and provisioned.
    • IP connectivity has been verified between all nodes of the Contrail Controller.
    • You can access the Contrail user interface at http://nn.nn.nn.nn:8080, where nn.nn.nn.nn is the IP address of the configuration node server that is running the contrail-webui service.

    To configure BGP peering in the control node:

    1. From the Contrail Controller module control node (http://nn.nn.nn.nn:8080), select Configure > Infrastructure > BGP Peer; see Figure 1.

      Figure 1: Configure> Infrastructure > BGP Peer

      Configure> Infrastructure > BGP

      A summary screen of the control nodes and BGP peers appears; see Figure 2.

    2. (Optional) The global AS number is 64512 by default. To change the global AS number, on the BGP Peer summary screen click the Global ASN button and enter the new number.
    3. To configure control nodes and BGP peers, on the BGP Peer summary screen, click the Create button. The Create BGP Peer window appears; see Figure 3.

    4. On the Create BGP Peer window, click the BGP Peer button to add a new BGP peer or click the Control Node button to add control nodes.

      For each node to add, populate the fields with values for your system. See Table 1.

      Table 1: Create BGP Peer Fields




      Enter a name for the node being added.


      The IP address of the node.

      BGP Port

      The default is 179; change if needed.

      Autonomous System

      Enter the AS number for the node. (BGP peer only)

      Router ID

      Enter the router ID.

      Vendor ID

      Required for external peers. Populate with a text identifier, for example, “MX-0”. (BGP peer only)

      Address Family

      Enter the address family, for example, inet-vpn

      Available Peers

      Displays peers currently available.

      Configured Peers

      Displays peers currently configured.

    5. Click the OK button to add each node that you configure.
    6. To configure an existing node as a peer, select it from the list in the Available Peers box, then click >> to move it into the Configured Peers box.

      Click << to remove a node from the Configured Peers box.

    7. You can check for peers by starting at Monitor > Infrastructure > Control Nodes; see Figure 4.

      On the Control Nodes screen, click any hostname from the memory map to view its details; see Figure 5.

    8. Click the Peers tab to view the peers of a control node; see Figure 6.
