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 and works on the application layer of OSI model. RIP uses port number Hop Count : Hop count is the number of routers occurring in between the source and destination network. The path with the lowest hop count is considered as the best route to reach a network and therefore placed in the routing table. RIP prevents routing loops by limiting the number of hopes allowed in a path from source and destination. The maximum hop count allowed for RIP is 15 and hop count of 16 is considered as network unreachable.

Routing Protocol Basics

Routing Information Protocol (RIP)

The routing table will ultimately determine the exit inter- face to forward the packet and the router will encapsulate that packet in the appropriated data link frame for that outgoing interface. Wikiversity has learning resources about Routing. Some routing protocols, which the number of routers between a router and the destination netwo. The maximum hop count allowed for RIP is 15 and hop count of 16 is considered as network routnig

In the next chapter, we will examine the configuration of static routes and introduce the IP rout- ing table. ;df to Packet Use the Packet Tracer Activity to practice configuring summary routes and default routes. Every router makes its decision alone, based on the information it has in its own routing table. For other uses, see Routing disambiguation.

You can open Packet Tracer Activity 1! Each router in the path from source to destination performs this same process of decapsulation, and then re-encapsulation, Protocols! Network Routing: Algorith. Note: The static route displays the route as directly connected.

Taking notes is an important way to help your understanding grow over time. Most of these are summarized routes.

Bibliographic Information

A routed protocol is any network layer protocol that provides enough information in its network layer address to allow a packet to be forwarded from one host to another host based on the addressing scheme, without knowing the entire path from source to destination. Routed protocols define the format and use of the fields within a packet. Packets generally are conveyed from end system to end system. Almost all network layer protocols and those that are layered over them are routable, with IP being an example. Data Link protocols such as Ethernet are necessarily non-routable protocols , since they contain only a link-layer address, which is insufficient for routing: some higher-level protocols based directly on these without the addition of a network layer address, such as 'NetBIOS', are also non-routable. Routing protocols are used in the implementation of routing algorithms to facilitate the exchange of routing information between networks, allowing routers to build routing tables dynamically.


Decapsulates the Layer 3 packet by removing the Layer 2 frame header and trailer. There is still one more command that we need to enter, on the router with the DCE cable. The topic of host routes is discussed in another course. The routing table also includes the interface to be used conceots forward the packet.

Discard Route A common configuration in many networks routung to have a static default route on the edge router for- warding packets to the ISP. The maximum hop count allowed for RIP is 15 and hop count of 16 is considered as network unreachable. The internal physical architecture will differ from model to model? By now, you should be very familiar with some tools that can help you isolate routing problems!

  1. Chapter1 also includes a review of basic Cisco IOS commands. Because 24 bits match the Click Disable Debug in protocils figure. These features mean that link state algorithms scale better to larger networks.👩‍🔬

  2. Therefore, Cisco IOS, and the process moves on to the next route in the routing table. The entire routing table is included with the routing table? Flash is used as permanent storage for the operating system. Verifying Router Bootup Process The show version command can be used to help verify and troubleshoot some of the basic hard- concepst and software components of the router.
