Answer» Correct option is (c) The route is inaccessible Easy explanation: You cannot have 16 HOPS on a RIP network by DEFAULT, because the MAX default hops POSSIBLE is 15. If you receive a route advertised with a metric of 16, this means it is inaccessible.

Discussion

86.	Two connected routers are configured with RIP routing. What will be the result when a router receives a routing update that contains a higher-cost path to a network already in its routing table?(a) The updated information will be added to the existing routing table Debug IP rip(b) The update will be ignored and no further action will occur Debug IP route(c) The updated information will replace the existing routing table entry(d) The existing routing table entry will be deleted from the routing table and all routers will exchange routing updates to reach convergenceI had been asked this question by my college professor while I was bunking the class.My doubt is from RIP v1 in division Networking of Computer Network
Answer» The correct option is (b) The update will be ignored and no further action will occur Debug IP route The explanation: When a routing update is received by a ROUTER, the router first checks the administrative DISTANCE (AD) and always chooses the route with the lowest AD. However, if two routes are received and they both have the same AD, then the router will choose the one route with the lowest metrics, or in RIP’s case, hop COUNT.

Answer» CORRECT answer is (d) Both RIPv1 and RIPV2 Explanation: Both RIPv1 and RIPv2 SUPPORT a maximum hop COUNT of 15 because they use 4-bits to store this value. RIPv1 USES classful routing whereas RIPv2 uses classless routing. The routing updates are broadcasted over the network. It notifies routers about the update so that they update their own routing tables.
