Configure a BGP Peer

A branch or a data center ION device can exchange routing information via BGP. A branch ION device supports only classic peers, whereas a data center ION device supports core, edge, and classic peers. Irrespective of the type of peers configured, the ION device installs the learned routes.
  1. Configure the remote AS number and type of BGP peer.
    1. Select
      Map
      Claimed Devices
      Select a device
      Routing
      Create Peer
      .
    2. On the
      Info
      tab, enter a name and optionally description and tags.
    3. Enter the
      Remote AS Number
      .
      The web interface displays converted values of the AS number entered. If the number entered is an A.B format, the web interface displays the corresponding 32-bit conversion below the entered value. If the number entered is a 32-bit format, the web interface displays the corresponding A.B value below the entered value.
    4. From the
      Peer Type
      drop-down, select
      Classic
      .
      The
      Peer Type
      option is available only for data center ION devices.
      When you configure a core or edge peer, the device automatically generates a route map for the peer. You can leave the route map as is or clone and modify it for your peer.
    5. (Optional)
      Specify the
      Update Source
      IP Address.
      You need to specify the
      Update Source
      IP Address only if there is more than one multi-hop.
    6. Toggle
      Scope
      to
      Local
      or
      Global
      .
      Local indicates that prefixes will not be advertised.
    7. Select the
      Shutdown
      check box if you do not need to use the created peer.
      The
      Shutdown
      check box is deselected by default.
  2. On the
    Route Maps
    tab, select a route map from the
    Route Map In
    and
    Route Map Out
    drop-downs to filter incoming or outgoing routes.
  3. Configure overrides for global options or inherit device global configuration.
    1. On the
      Advanced Options
      tab, select
      Yes
      to inherit device global configuration or select
      No
      to configure global configuration overrides.
    2. Configure overrides for global options.
      • (Optional)
        Keepalive Time
        —Enter a keep-alive time between 3 - 60 seconds. If you have configured a BGP peer, the device uses the value specified in the BGP peer configuration. If you do not configure a BGP peer or do not specify a value in the BGP global configuration, the keep-alive time defaults to 30 seconds.
      • (Optional)
        Hold Time
        —Enter a hold time between 3 - 600 seconds. The hold time needs to be three times greater than the keep-alive time. If you have configured a BGP peer, the device uses the value specified in the BGP peer configuration. If you have not configured a BGP peer, the device uses the value from the BGP global configuration. If you do not configure a BGP peer or do not specify a value in the BGP global configuration, the Hold Time defaults to 90 seconds.
      • (Optional)
        Advertise Interval
        — Enter an advertisement interval between 0 - 600 seconds. The default is 1 second.
      • (Optional)
        Peer Retry Time
        —Enter a peer retry time between 0 - 65535 seconds. The default is 120 seconds.
      • (Optional)
        Multihop Limit
        —Enter a multi-hop limit between 1 - 255 hops. The default is 1 hop.
      • (Optional)
        MD5 Secret
        —Enter a password of 1 - 32 characters. The default is 0. MD5 password specified shall be applied to the messages exchanged with the peer.
      • (Optional)
        Local AS Number
        —Enter a number between 1 and 4294967295 or as A.B, where A and B are both numbers between 1 and 4294967295. The web interface displays converted values of the AS number entered. If the number entered is an A.B format, the web interface displays the corresponding 32-bit conversion below the entered value. If the number entered is a 32-bit format, the web interface displays the corresponding A.B value below the entered value.
  4. Review the BGP peer configuration.
    The
    Summary
    tab displays the BGP peer configuration. Make changes if needed and
    Save & Exit
    .
