1 Introduction
The Bandrich K530S 4G LTE broadband router with service over the
Sprint NW is an inexpensive solution for business continuity to provide a
backup connection to the internet/VPN in case of failure of the primary
connection.
This document provides a high level overview on how to configure the
K530S and the customers edge router to achieve this redundant
connection to internet/VPN.
2 Overview
The K530S is assigned a dynamic routable I P address by the Sprint NW.
In order to use the K530S as a backup connection to a secondary ISP, it
is desirable to configure it in bridge mode. This way the K530S can be
connected to the customer’s edge router in which case the edge router
gets the IP address that is assigned to the K530S.
The edge router can then be configured to use this interface as a default
static route to the secondary ISP (Sprint).
Static route tracking allows customer to use an inexpensive connection to
a secondary Internet service provider (ISP) in the event that the primary
leased line becomes unavailable.

The customer edge router can be configured with a static route tracking
feature to track the availability of the static route to the primary ISP.
In case of a failure in the static route to the primary ISP, the static route
tracking feature will remove it from the routing table and replace it with a
backup route.
Please refer to your specific router admin guide on how to configure static
route tracking.
This document provides details on how to configure the K530S in bridge
mode as well a s h o w t o co nf i g ur e t h e e dg e r o ut er wit h a st at i c r o ut e t o the
K530S.
Note: The conf iguration i s for redundancy or bac kup purposes only and
not for load sharing across the two interfaces. Outgoing traffic uses the
primary ISP and then the secondary ISP, if the primary fails. Failure of the
primary ISP causes a temporary disruption of traffic.
3 Components
The following components are required for this redundant connection for
business continuity:
• Edge router with at least one available outside L3 Ethernet
interface to connect to K530S router and for configuring the
redundant route to the internet
• K530S LTE router activated on Sprint 4G LTE network with a
dynamic routable IP
• Connection from ERDM (Ericsson Remote Device Manager)
to the K530S over the Sprint NW via the assigned dynamic IP
4 Instructions
4.1 K530S in Bridge mode via local connection
Connect to the K530S over the laptop Ethernet interface and launch the
browser to
http://192.168.1.1
Login to the K530S administration GUI using the provided credentials.

Navigate to ‘Advanced’ tab and then to the ‘Operation’ tab.
Set the operation mode to ‘Bridge’ and click on ‘Apply’.
The K530 will reboot and come up in bridge mode.
4.2 K530S in bridge mode via ERDM
Connect to ERDM using
https://erdm.ericyhost.com/erdm
Login with your ERDM tenant credentials.
Connect to the K530S from the ERDM. Go to advanced view, then select
‘retrieve all device settings’ from drop down.
Once that completes, select ‘settings for entire parameter l ist’ from dr op
down. Then scroll down to parameters grouped under X_0026FA_RF.
Under that, there is a parameter called ‘OperationMode’.
Change the parameter value (router or bridge) by putting a new value in
the ‘override’ column. Then highlight that parameter row, and select ‘send
marked setting’ from drop down.
This will update the device with new parameter value.

4.3 Remote Access to K530S
If no local access to the K530S and no connection via ERDM either, one
can connect to it remotely if the ‘remote management’ is enabled.
http://<K530S-IP-Address>:8080
To enable remote management, connect to the K530S from the ERDM.
Go to advanced view, then select ‘retrieve all device settings’ from drop
down.
Once that completes, select ‘settings for entire parameter l ist’ from dr op
down. Then scroll down to parameters grouped under X_0026FA_RF.
Under that, there is a group called ‘RemoteAccess’ with t wo parameters:
enable & port
Change the parameter value by putting a new val ue in t he ‘override’
column. Then highlight that parameter row, and select ‘send marked
setting’ from drop down.
This will update the device with new parameter value.

Once remote management is enabled, connect to the K530S directly from
the browser: http://<K530S-IP-Address>:8080
4.4 Configure edge router with redundant static route
A static IP address is not necessary to get the Cisco router to successfully
receive the IP address from the K530S. A static IP address may be
required or desired to support VPN tunnels, but not to merely get the IP
address from the K530S to the Cisco router. For that, a dynamic IP
address will suffice.
The Ethernet interface on the Cisco router should be configured for “IP
ADDRESS DHCP.” This will enable th e DHCP c lien t on the Cisco router
to request an IP address from the K530S DHCP server.
Once the interface gets the IP address from the DHCP server the
interface should be configured correctly.
NOTE: It is not recommend to hard-code the IP address and subnet mask
into the Ethernet interface. While this is standard procedure for wireline
network configuration, wireless network configurations require using
DHCP instead. The reason is that the Sprint network or the K530S could
potentially change something in the DHCP server response that conflicts
with what the admin hard-coded in the Cisco router interface
configuration.
If this interface is used in a static route or default route the statement
should use “DHCP” instead of the IP address or the interface name. If t he
IP address or interface name is used the route will not work. Therefore,
the route statement would look something like this:

• IP route 192.168.130.0 255.255.255.0 DHCP
Since the interface is using DHCP the route statement must also use
DHCP.
