Configure Interfaces

With the configuration data in hand, it is now possible to configure TNSR interfaces for basic IP level connectivity.

From within the TNSR CLI (Entering the TNSR CLI), enter configuration mode and setup the interfaces using this example as a guide:

tnsr# configure terminal
tnsr(config)# interface GigabitEthernet0/14/1
tnsr(config-interface)# description WAN
tnsr(config-interface)# ip address 203.0.113.2/24
tnsr(config-interface)# enable
tnsr(config-interface)# exit
tnsr(config)# interface GigabitEthernet0/14/2
tnsr(config-interface)# description LAN
tnsr(config-interface)# ip address 10.2.0.1/24
tnsr(config-interface)# enable
tnsr(config-interface)# exit
tnsr(config)# exit
tnsr#

In this sample session, both interfaces were configured with an appropriate description for reference purposes, an IP address/subnet mask, and then placed into an enabled state.

If other hosts are present and active on the connected interfaces, it will now be possible to ping to/from TNSR to these networks.

Tip

After making changes, don’t forget to save them to ensure they persist for the next startup by issuing the configuration copy running startup command from with in config mode. See Saving the Configuration for more information.

DHCP Client Example

The previous example was for a static IP address deployment.

To configure a TNSR interface to obtain its IP address via DHCP as a client, follow this example instead:

tnsr# configure terminal
tnsr(config)# interface GigabitEthernet3/0/0
tnsr(config-interface)# dhcp client ipv4
tnsr(config-interface)# enable
tnsr(config-interface)# exit
tnsr(config)# exit
