The show ip protocols command displays the IPv4 routing protocol settings currently configured on the router. This output displayed in Figure 1 confirms most RIP parameters including:
1. RIP routing is configured and running on router R1.
2. The values of various timers; for example, the next routing update, is sent by R1 in 16 seconds.
3. The version of RIP configured is currently RIPv1.
4. R1 is currently summarizing at the classful network boundary.
5. The classful networks are advertised by R1. These are the networks that R1 include in its RIP updates.
6. The RIP neighbors are listed including their next-hop IP address, the associated AD that R2 uses for updates sent by this neighbor and when the last update was received from this neighbor.
