What command modifies the administrative distance of RIP?

The command used to modify the administrative distance of the Routing Information Protocol (RIP) in Cisco IOS is "distance value." This command is entered in the router's configuration mode, and it allows the network designer to set an administrative distance (AD) value for RIP, which is essential in determining how routers prioritize incoming routing information from different routing protocols.

By default, RIP has an administrative distance of 120. Adjusting this value can influence the routing table by either making RIP routes more or less preferred compared to other routing protocols. For example, if you set a lower distance value for RIP than that of another routing protocol such as OSPF (which has an AD of 110), it would make RIP routes more preferred, and they would take precedence in the routing table.

Using "distance value" is the most specific and accurate way to make these adjustments effectively, reflecting the intended functionality within the routing protocol settings.
