When multiple routing protocols have a route to the same destination network what determines which route is installed in the routing table?

When multiple routing protocols have a route to the same destination network what determines which route is installed in the routing table?

When a routing table contains multiple routes to the same destination, the system always uses the table entry with the lower metric value. The term hop count refers to the distance between two networks, based on the number of routers that packets must pass through on the way from the source to the destination.

Which routing protocol will be considered as the best route?

Eigrp and Ospf have equal importance. It is easy, if you want fast convergence you need a “Link State Routing Protocol”. The IETF recommendation, for your case, is OSPF.

How does RIPv2 send routing updates?

RIPv2 sends routing updates via multicast address 224.0. 0.9. Cisco routers don’t enable RIPv2 by default. To use RIPv2, you must use the ver 2 command in RIP Router Configuration Mode.

What is the first criteria that is used by the OSPF routers to select the best route to be installed in the routing table?

The route with the lowest value for cost is chosen as the best route. If there are multiple routes to a network with the same route type and cost, it chooses all the routes to be installed in the routing table, and the router does equal cost load balancing across multiple paths.

What type of routing protocol is RIPv2?

distance-vector
Introduction: The Routing Information Protocol (RIP) is a distance-vector,interior gateway (IGP) routing protocol used by routers to exchange routing information. RIP uses the hop count as a routing metric.

When to use administrative distance in routing protocol?

If a router learns about a destination from more than one routing protocol, administrative distance is compared and the preference is given to the routes with lower administrative distance. In other words, it is the believability of the source of the route.

When do you need to change routing protocols?

Simple routing protocols work well for simple networks, but as networks grow and become more complex, it may be necessary to change the routing protocols. Often, the transition between routing protocols takes place gradually, so there are multiple routing protocols that are operating in the network for variable lengths of time.

Which is multicast routing protocol do you use?

Multicast routing protocols build a loop-free distribution tree of routers that connect the multicast sources and receivers. In this experiment, we will use the Protocol-Independent Multicast (PIM) protocol. (Here, “protocol-independent” means that you can use it together with any unicast routing protocol.)

What happens if the most preferred route fails?

If the most preferred route fails, the next best route (according to administrative distance) succeeds on the next attempt. The other solution is for the routing protocol that failed to install its route in the table to hang on to the route, and tell the routing table process to report if the best path fails.
