Goal Goal
To use the 63xx-series router's cellular modem as a backup WAN connection for the primary
WAN Ethernet port. The 63xx-series router will use the WAN Ethernet port as its main Internet
connection, and will fail over to the cellular modem if the primary connection goes down.
Setup Setup
This article assumes the LAN ports are operating under default settings, which provide DHCP
connectivity to devices connected to the 63xx-series router's LAN ports. For more details on the
default settings of the 63xx-series router, see the Default Settings Default Settings section of the SR User's
Manual .
For this setup, you will need the 63xx-series router with both a primary WAN Ethernet
connection, and a cellular modem connection.
Sample Sample
The sample configuration below shows a 63xx-series router with two internet connections. The
WAN Ethernet interface will be used as the primary Internet connection. The 63xx-series router
is setup to test the WAN Ethernet connection twice every minute. If three sequential tests fail,
then the 63xx-series router will restart the WAN Ethernet connection, and failover to the cellular
modem's Internet connection until the WAN Ethernet connection is re-established.
Summed up, if a 63xx-series router's primary WAN connection fails, with the below
configuration the 63xx-series router will failover to the cellular modem in under 2 minutes.
