    RIP runs only on the interfaces attached to the specified network. For an interface not on the specified network, RIP neither receives/sends routes on it nor forwards interface route through it. You need to specify the network after enabling RIP to validate RIP on a specific interface. For a single process, the network 0.0.0.0 command can enable RIP on all interfaces, but the command is not applicable in case of multi-process.

    When a valid RIP route is received, the system adds a metric to it and then installs it into the routing table. The metric of the route received on the configured interface is then increased. If the sum of the additional metric and the original metric is greater than 16, the metric of the route will be 16.

    Based on its LSDB, an OSPF router calculates the shortest path tree with itself being the root, and uses it to determine the next hop to a destination. Through adjusting the SPF calculation interval, you can protect bandwidth and router resources from being over-consumed due to frequent network changes. With this command configured, when network changes are not frequent, SPF calculation applies at the minimum-interval.
