An example of how to configure the interfaces for the LAN network and the provider networks.

   vyatta@vyatta# set interfaces dataplane dp0p33p1 address '10.11.0.1/24'

   vyatta@vyatta# set interfaces dataplane dp0p33p1 description 'LAN'

2. Configure the interface for the Provider A network.

   vyatta@vyatta# set interfaces dataplane dp0p161p1 address '10.10.2.1/24'

   vyatta@vyatta# set interfaces dataplane dp0p161p1 description 'Provider A'

3. Configure the interface for the Provider B network.

   vyatta@vyatta# set interfaces dataplane dp0p224p1 address '10.10.3.1/24'

   vyatta@vyatta# set interfaces dataplane dp0p224p1 description 'Provider B'

4. Configure the interface for the Provider C network.

   vyatta@vyatta# set interfaces dataplane dp0p256p1 address '10.10.4.1/24'

   vyatta@vyatta# set interfaces dataplane dp0p256p1 description 'Provider C'

5. Commit the configuration.

   vyatta@vyatta# commit
