Understanding Source IP Filtering with Address Pools in TDF Domains for IP-Based Subscribers

The TDF domain that is assigned to an IP-based subscriber can identify a set of source IP addresses of packets that need to undergo TDF processing. These sets of IP addresses are configured using address pools. Address pools can then be added to a TDF domain.

Address pools contain a set of IP addresses specified by network prefixes. You can configure more than one set of addresses in an address pool. You can configure address pools to contain IPv4 addresses or IPv6 addresses, but not both.

You can configure an address pool as a default pool, and a TDF domain uses the default address pool when an address pool is not explicitly specified for the TDF domain.
