What layer is RIP and OSPF?
RIP runs over UDP 520 while OSPF has its own transport mechanism. Routing is done in the IP layer(layer 3 of the router), whereas RIP/OSPF helps in table formation by running in the application layer.
When would you use OSPF over RIP?
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. OSPF multicasts link-state updates and sends the updates only when there is a change in the network.
Why RIP is application layer protocol?
Routing Information Protocol (RIP) is a dynamic routing protocol which uses hop count as a routing metric to find the best path between the source and the destination network. It is a distance vector routing protocol which has AD value 120 and works on the application layer of OSI model. RIP uses port number 520.
What is the relationship between transport layer and network layer?
For example, the network layer lies just below the transport layer in the protocol stack. Whereas a transport layer protocol provides logical communication between processes running on different hosts, a network layer protocol provides logical communication between hosts. This distinction is subtle but important.
What are the similarities and differences between EIGRP and OSPF?
The main difference between these protocols is that EIGRP exchanges the complete routing information just one time when the neighbouring routes are established after that it only tracks the changes. On the contrary, OSPF keeps track of the whole topology database of all the connection in the database consistently.
Is RIP a layer 3 protocol?
RIP works at layer 3 and sends routing information across the network.
What is the major difference between the Internet Layer and transport layer?
The basic difference between network layer and transport layer is that transport layer protocol provides logical communication between processes running on different hosts , whereas network layer protocol provides logical communication between hosts.
What makes Rip and OSPF layer 3 protocol?
RIP and BGP use UDP/TCP just like FTP. They exchange information that’s used by Layer 3 of the OSI model sure, but you can use FTP to send some routes into a UNIX based device to populate the routing table also. Does that make FTP a layer 3 protocol in that instance?
When do you need to use OSPF for routing?
OSPF is one choice for a routing protocol, but it is an industry standard, and just about every business-grade router supports it. It is also very well understood by most network engineers, and fairly simple to configure. Share Improve this answer
When do you use ICMP instead of OSPF?
ICMP is used for diagnostic purposes and for testing OSI L3 connectivity (IP level) using TCP or UDP would mean testing at OSI layer 4-7 ( above IP layer) it would mean involving upper layers OSPF is a routing protocol of type IGP interior gateway protocol and it is used to buid routing tables.
Is there a data layer for OSPF / EIGRP?
OSPF/EIGRP do not use a data layer protocol for establishing a session, they work directly over layer 3 so it makes a lot more sense when speaking of these protocols. If it were a test I’d go wtih layer 3, but its just a model.
