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

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.

    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.

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

  3. Specify the network prefix for the address pool for the configured protocol family.

    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 and

  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.
