Route Management Redundancy Overview
Route management redundancy provides redundancy in case the next-hop gateway (the router) becomes unreachable.
When you configure your Ethernet interfaces, you specify a default next-hop gateway (router) in your default Ethernet interface configuration. You can then configure additional Ethernet interfaces with static routes to different next-hop gateways. The CTP device monitors the reachability of the next-hop gateway. If the gateway becomes unreachable, the CTP software removes the configured static route to the gateway from its routing table. You can also specify priority for static routes by assigning a metric. If the default route is unreachable, then the route with the lowest metric is used.
