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? Correct Answer The update will be ignored and no further action will occur Debug IP route

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.

Consider a computer network using the distance vector routing algorithm in its network layer. The partial topology of the network is as shown below. The objective is to find the shortest-cost path from the router R to routers P and Q. Assume that R does not initially know the shortest routes to P and Q. Assume that R has three neighbouring routers denoted as X, Y, and Z. During one iteration, R measures its distance to its neighbours X, Y, and Z as 3, 2, and 5, respectively. Router R gets routing vectors from its neighbours that indicate that the distance to router P from routers X, Y, and Z are 7, 6, and 5, respectively. The routing vector also indicates that the distance to router Q from routers X, Y, and Z are 4, 6, and 8, respectively. Which of the following statement(s) is/are correct with respect to the new routing table of R, after updation during this iteration ?

Consider the following statements about the routing protocols. Routing Information Protocol (RIP) and Open Shortest Path First (OSPE) in an IPv4 network. I. RIP uses distance vector routing II. RIP packets are sent using UDP III. OSPF packets are sent using TCP IV. OSPF operation is based on link-state routing Which of the statements above are CORRECT?
A group of 2m - 1 routers are interconnected in a centralized binary tree, with router at each tree node. Router I communicate with router J by sending a message to the root of the tree. The root then sends the message back down to J. Then find the mean router-router path length.
Which two of the following are true regarding the distance-vector and link-state routing protocols?
1. Link state sends its complete routing table out all active interfaces on periodic time intervals.
2. Distance vector sends its complete routing table out all active interfaces on periodic time intervals.
3. Link state sends updates containing the state of its own links to all routers in the internetwork.
4. Distance vector sends updates containing the state of its own links to all routers in the internetwork.
A network administrator views the output from the show ip route command. A network that is advertised by both RIP and IGRP appears in the routing table flagged as an IGRP route. Why is the RIP route to this network not used in the routing table?

You get a call from a network administrator who tells you that he typed the following into his router:
Router (config) #router ospf 1Router (config-router) #network 10.0.0.0 255.0.0.0 area 0
He tells you he still can't see any routes in the routing table. What configuration error did the administrator make?
