Objective


  • The configuration of BGP peering with Advanced Routing Engine (ARE) is explained under Enable Advanced Routing.
  • This article provides an example of BGP configuration using the topology below.

Environment

Procedure


  1. Basic Network Setup

    1. Create a Logical Router

      1. Navigate to Network > Routing > Logical Router > Add 
      2. Assign a name as shown in the figure below:
        BGP2.png
      3. save the config by clicking OK

  2. Assign the Logical Router to Interfaces 

    1. Navigate to Network > Interfaces > Ethernet

    2. Ensure the relevant interfaces have the newly created logical router as shown in the figure below

  3. Configure BGP peering 

    1. Navigate to Network > Routing > Logical Router > click ENT > BGP > General
    2. Ensure the following fields are as below:
      1. Enabled: Checked
      2. Router ID: 172.16.1.2
      3. Local AS: 64540
      4. Install Route: Checked

    3. Navigate to Peer Group | configure the parameters as shown in the figure below:
      1. Name: ISPs
      2. IPv4 Address Family: default
        NOTE: IPv4 Address Family is the only Routing Profile needed for peering, if you don't have the default option, create a new one by clicking on the drop down option then New AFI Profile, use the following parameters. Otherwise, skip this portion:
        • Name: MyIPv4AddFamily
        • Enable: check
        • OK: to save
        • Attach the profile MyIPv4AddFamily to IPv4 Address Family

      3. To configure the BGP peers, click Add as highlighted above
      4. Use the following parameters for the ISP1 peering:
        1. Name: ISP1
        2. Peer AS: 64512
        3. Local Address > Interface: ethernet1/1
        4. Peer Address: 172.16.1.1

        5. Click OK to save the configuration for ISP1
      5. Repeat previous step (3.c.iv) for ISP 2 using the following parameters:
        1. Name: ISP1
        2. Peer AS: 64513
        3. Local Address > Interface: ethernet1/2
        4. Peer Address: 172.16.2.1

      6. Save changes using OK 
      7. Commit changes

  4. Verification of Functionality 

    1. BGP peering can be confirmed from Network > Routing > Logical Router > More Runtime Stats > BGP > Peer as shown in the figure below:
      bgp8.png


    2. BGP RIB routes learned from the peer can be verified from Network > Routing > Logical Router > More Runtime Stats > BGP > Route as shown in the figure below:
      bgp10.png

    3. BGP routes installed into the routing table can be examined from Network > Routing > Logical Router > More Runtime Stats > Routing as shown in the figure below:
