Configure Reliable Static Routing on the ES440

Configuring Reliable Static Route (RSR) on the ES440 reduces airtime usage by

directing traffic between the ES440 and AirVantage Management Service over

the wired network when the primary Internet connection is active and over the

wireless connection when it becomes inactive.

AirVantage Management Service can track the status of RSR and indicate on the

Failover Status dashboard widget whether your Internet connection is using the

primary or failover WAN link.

ip dhcp-client default-router distance 200

ip route 0.0.0.0 0.0.0.0 192.168.13.31 201

All gateways discovered by DHCP have a 200 metric

Add static route to Internet through ES440,

with a larger metric than gateways discovered by DHCP.

This route is not used until the above route is removed.
