Note that this is a cumbersome and unreliable way of achieving automatic rerouting because it works only when the route to the next hop disappears, not when the next hop itself becomes unavailable. So, for example, if these two next hop routers were connected through different physical interfaces, and one of those interfaces went down, the router could switch to the router with the higher distance. But if both devices were on the same directly connected Ethernet segment, this would not provide a fail-over. So while this method is useful for some limited applications, in general it is better to use a dynamic routing protocol such as RIP, EIGRP, or OSPF, which are d...
