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.

Overview
The K530S is assigned a dynamic routable IP 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.
