Which of the following technologies can be used in distance vector routing protocols to prevent routing loops?
Cisco uses DUAL FSM (EIGRP) to make sure that on a global level a route is recalculated when the possibility exists that it might cause a routing loop. In essence, this attempts to prevent routing loops. Other algorithms used in path calculation are the Bellman-Ford (shortest path) and Ford-Fulkerson (maximum flow).
Which mechanism helps to avoid routing loops by advertising a metric of infinity?
route poisouning
What is poison reverse?
Poison reverse is a technique used in computer networking to prevent routing loops in distance-vector routing protocols. It involves advertising a route back to the neighbor it was learned from with an infinite metric to indicate that the route is unreachable. This helps to avoid packets being sent in circles during routing updates.
What is the maximum number of hops OSPF allows?
OSPF allows a maximum hop count of 65,535 in its routing updates to prevent routing loops and ensure network stability. Beyond this limit, OSPF will consider the route unreachable.
What is split horizon rule?
The split horizon rule is a technique used in computer networking to prevent routing loops in distance-vector routing protocols. It prohibits a router from advertising a route back onto the interface from which it was learned. This helps to improve the stability and efficiency of the network.

What is the process of sending routes from one routing protocol to another routing protocol?
The process of sending routes from one routing protocol to another is known as route redistribution. This involves configuring a router to accept routes learned from one routing protocol (such as OSPF or EIGRP) and advertise them into another routing protocol. To do this, network administrators typically use redistribution commands in the router's configuration, specifying the source and target protocols. Care must be taken to manage metrics and prevent routing loops during this process.
What is different between router and routing?
*router is a device use to route communication or connection *routing is the process *router is a device use to route communication or connection *routing is the process
Identify the command used to display information on routing-table updates and route-cache updates?
route#debug ip routing
What is the characteristic of a classless routing protocol?
A classless routing protocol can route between subnets
What is paper routing?
Having a paper route.
Which commands isolate routing table problems?
debug ip routing show ip route
