Which protocol has a limit of 15 hops?
RIP
RIP is a standardized vector distance routing protocol and uses a form of distance as hop count metric. It is a distance vector. Through limiting the number of hop counts allowed in paths between sources and destinations, RIP prevents routing loops. Typically, the maximum number of hops allowed for RIP is 15.
Which routing protocol would you prefer if the network diameter is less than 15 hops?
Which routing protocol has a maximum network diameter (hop count) of 15? 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.
Why hop count is 15 in RIP?
Because in computing, binary form is used for storing numbers. In this case the maximum binary number in four positions would be 15 (1111). So they reserved four digits to count the hops. It seemed to be enough at the time they developed RIP.
How many hops can OSPF do?
15-hop limitation OSPF has no hop limitation. You can add as many routers to a network as you want.
What are 3 common routing protocols?
Router protocols include:
- Routing Information Protocol (RIP)
- Interior Gateway Protocol (IGRP)
- Open Shortest Path First (OSPF)
- Exterior Gateway Protocol (EGP)
- Enhanced Interior Gateway Routing Protocol (EIGRP)
- Border Gateway Protocol (BGP)
- Intermediate System-to-Intermediate System (IS-IS)
Which protocol should you select if the network diameter is more than 17 hops?
RIPv2protocol
Which protocol should you select if the network diameter is more than 17 hops? Explanation: RIPv2protocol should you select if the network diameter is more than 17 hops.
Which protocol should you select if network diameter is more than 17 hops?
What is the main reason of using RIP?
Stands for “Routing Information Protocol.” RIP is a protocol used by routers to exchange routing information on a network. Its primary functions are to 1) determine the most efficient way to route data on a network and 2) prevent routing loops.
What is the maximum hop count for RIP?
15
The maximum hop count for RIP routers is 15. Networks with a hop count of 16 or more are considered unreachable.
What are two main advantages of OSPF over RIP?
Pros: OSPF routing protocol has complete knowledge of network topology, allowing routers to calculate routes based on incoming requests. OSPF protocol has no limitations in hop count, unlike RIP protocol that has only 15 hops at most. So OSPF converges faster than RIP and has better load balancing.
Which routing protocol is used today?
While a variety of IGPs are currently used, about the only EGP in use today is the Border Gateway Protocol (BGP). This is the routing protocol of the Internet. From talking with administrators who manage a variety of networks, the consensus is that OSPF is becoming the most popular interior routing protocol today.
What routing protocol should I use?
Many network engineers believe that EIGRP is the best choice for a routing protocol on private networks because it offers the best balance between speed, scalability and ease of management.
What is the maximum number of hops a packet can pass?
The hop count, expressed in a decimal from 1 to 15, describes the number of routers the packet will have to pass before arriving at its destination. Since the maximum hop count is 15, it may be difficult to reach a slower network represented with a large hop count.
Is there a limit to the hop count in Rip?
Some routing protocols DO have hop count limits, namely RIP has a limit of 15, and IGRP has a limit of 100 by default (configurable up to 255). Hop count limitations also exist in general owing to the TTL field in an IP datagram, but this is not due to the routing protocol.
What’s the maximum hop count for a Cisco router?
The maximum hop count for RIP routers is 15. Networks with a hop count of 16 or more are considered unreachable. Cisco networks using RIP have a slow recovery time after a topology change.
How are TTL and hop count used in routing?
There is TTL which is used by the IP protocol to minimize the impact of any packet that happens to get into a routing loop. And there is hop count which is used by some routing protocols to determine if something is so far away that it should no longer be advertised.
