6 - Private Route
Setting this secondary network IP address to be a private route causes the IP address and network to not be advertised
in the RIP information.
Default: [disabled]
7 - Route Cost
The Route Cost option defines the amount of extra routing cost (in hops) to add to routes that are learned from this
Secondary network. This can be used in the case of multiple routes to artificially increase the cost of a less preferred
route so that it will be used only if the preferred route is not available. The cost will not be added (and thus not appear
in the route statistics) until a connection is made.
Default: [0]
