ADTRAN Routers with CradlePoint CBA750B Configuring the ADTRAN Router

In the example configuration below, the ip address dhcp command is used to configure the Ethernet

interface to the CBA750B to learn its IP address using DHCP, and assign it an administrative distance of

10. Additionally, the ip access-policy command is used to assign the Public2 ACP to the interface.

To configure the WAN failover Ethernet interface to the CBA750B, enter the following commands at the

specified command prompts:

(config)#interface ethernet 0/2

(config-eth 0/2)#ip address dhcp 10

(config-eth 0/2)#ip access-policy Public2

(config-eth 0/2)#no shutdown

Step 7: Configure the Primary Ethernet WAN Interface

Configure the primary Ethernet WAN interface with a static IP address and assign it the Public ACP

created in Step 4: Configure Policy Classes and Access Lists for Each WAN Connection on page 7 to allow

only HTTPS and SSH traffic through the interface for ADTRAN router management

In the example configuration below, the ip address command is used to configure the primary Ethernet

interface with a static IP address. Additionally, the ip access-policy command is used to assign the Public

ACP to the interface.

To configure the primary Ethernet interface, enter the following commands at the specified command

prompts:

(config)#interface ethernet 0/1

(config-eth 0/1)#ip address 198.51.100.1 255.255.255.192

(config-eth 0/1)#ip access-policy Public

(config-eth 0/1)#no shutdown

Step 8: Configure the Default Route to the WAN Gateway

Configure a default route to the WAN gateway. The default route is used as the destination for packets for

which no route is present. To set a static default route to the next-hop gateway, use the ip route command

from the Global Configuration mode:

(config)#ip route 0.0.0.0 0.0.0.0 198.51.100.2

Optional. Configuring WAN Failover with Network Monitor

Network monitor features for probe, track, and policy-based routing can be used to automatically detect

primary WAN failure and switch over to the wireless WAN failover interface for backup. This optional

configuration uses Internet Control Message Protocol (ICMP) probes to network servers to detect WAN

failures in addition to physical Ethernet interface disruptions.

WAN failover with network monitor provides an additional means of detecting primary WAN

failure. The wireless WAN failover configurations provided in Configuring the ADTRAN

Router for Wireless WAN Failover on page 5 must also be configured.
