Configuring a TDF Logical Interface

A TDF logical interface is distinct from other types of interfaces and is used to associate a TDF domain’s subscribers with an access interface in a virtual routing and forwarding (VRF) table and with a TDF service set. You need to configure one TDF interface logical interface (unit) for every TDF domain.

To configure a TDF interface, you configure one or more logical interfaces (units) for the interface:

  1. Configure a TDF logical interface. Repeat this step for each TDF domain.
  2. (Optional) Configure the maximum transmission unit (MTU) size for the TDF logical interface.
