Configuring Address Pools for Source-IP Filtering of IP-Based Subscribers

date_range 13-Jan-21

Address pools identify a set of IP addresses that a TDF domain for IP-based subscribers uses to determine which packets undergo TDF processing.

To configure address pools:

  1. Specify a name for the address pool.
    content_copy zoom_out_map
    [edit access address-assignment]
    user@host# set address-pools name
    

    The pool name can contain letters, numbers, and hyphens (-) and can be up to 63 characters long.

  2. Specify the protocol family (inet for IPv4 addresses and inet6 for IPv6 addresses) for the address pool.
    content_copy zoom_out_map
    [edit access address-assignment]
    user@host# set address-pools name family (inet | inet6)
    

    For example, to configure an address pool named mbg-pool1 with IPv4 addresses:

    content_copy zoom_out_map
    [edit access address-assignment]
    user@host# set address-pools mbg-pool1 family inet
    
  3. Specify the network prefix for the address pool for the configured protocol family.
    content_copy zoom_out_map
    [edit access address-assignment]
    user@host# set address-pools name family (inet | inet6) network [network-prefix] external-assigned
    
    Note:

    A address pool must have at least one network prefix configured. You can configure more than one network prefix by including the network statement multiple times.

    The external-assigned statement is required.

    For example, to configure an address pool with network prefixes 10.100.0.0/16 and 192.168.0.0/16:

    content_copy zoom_out_map
    [edit access address-assignment]
    user@host# set address-pools mbg-pool1 family inet network 10.100.0.0/16 external-assigned
    user@host# set address-pools mbg-pool1 family inet network 192.168.0.0/16 external-assigned
    
  4. (Optional) Specify that the address pool is the default pool.

    A TDF domain uses the default address pool to specify the source addresses of packets that undergo TDF processing when an address pool is not specified for the TDF domain.

    content_copy zoom_out_map
    [edit access address-assignment]
    user@host# set address-pools name default-pool
