RIP is an Interior Gateway Protocol and the most widely accepted routing protocol. It is also known by the name of the Unix daemon program routed. RIP is straightforward: it arranges to have routers to broadcast their entire current routing database periodically
OSPF is a link-state algorithm. OSPF specifies a class of messages called link-state advertisements (LSAs) that allow routers to update each other about the LAN and WAN links to which they are connected. When a change is made to the network, LSAs flow between routers.
OSPF routers receive link-state updates and store them in a topology database in memory.
OSPF networks as an end-station-to-router protocol. OSPF addresses all the deficiencies of RIP, without affecting connectivity to RIP based networks.

What layer does the routing protocols belongs to?
Rip and BGP is in Application layer Ospf is in Transport Layer
Is OSPF a classful or classless link-state routing protocol?
OSPF is a classless link-state routing protocol. RIP version 1 and IGRP are both classful distance vector routing protocols, EIGRP is a hybrid protocol that supports classless addressing.
What is br-rip?
Blu Ray Rip. Same as a DVD Rip but from a blu ray disc :)
What types of routing protocols allow routers to exchange information?
That would be a distance-vector routing protocol. Examples (taught at Cisco Academies) include RIP, IGRP (obsolete in the new version of the curriculum), and EIGRP - but those are only for IP, and there are also distance-routing protocols for other networking protocols, for example, RIP for IPX.
What is the method that a routing protocol uses to determine the best route to a destination network?
It depends on the routing protocol in use, for example RIP uses the hop-count to determine the best route where less hops is better, OSPF uses cost, EIGRP uses a composite metric (BW + Delay + Reliability + Load) etc.
At what layer in the osi model would you find protocols such as rip and ospf?
OSPF and RIP are used in the network layer of the ISO model.
Why we r using rip instead of ospf?
Could be because your routers do not support OSPF.
Which two of these are routing protocol?
Rip ospf
Which type of policy allows RIP routes to be placed into OSPF?
OSPF Export Policy [dsp]
The OSPF packet format has a checksum field but the RIP packet does not why?
RIP messages are wrapped in a UDP package, which already has a checksum.
What are the key characteristics of OSPF?
OSPF has the following features:Fast Convergence OSPF can detect and propagate topology changes faster than RIP. Count-to-infinity does not occur with OSPF.Loop-Free Routes OSPF-calculated routes are always loop-free.Scalability With OSPF, an AS can be subdivided into contiguous groups of networks called areas. Routes within areas can be summarized to minimize route table entries. Areas can be configured with a default route summarizing all routes outside the AS or outside the area. As a result, OSPF can scale to large and very large internetworks. In contrast, RIP for IP internetworks cannot be subdivided and no route summarization is done beyond the summarizing for all subnets of a network ID.Subnet Mask Advertised with the Network OSPF was designed to advertise the subnet mask with the network. OSPF supports variable-length subnet masks (VLSM), disjointed subnets, and supernetting.Support for Authentication Information exchanges between OSPF routes can be authenticated.Support for External Routes Routes outside of the OSPF AS are advertised within the AS so that OSPF routers can calculate the least cost route to external networks.
Which internal routing protocol would use if you needed to route between Cisco and non-Cisco equipment?
Open standard protocols: Rip or OSPF. They are not Cisco proprietary protocols.
What layer does the routing protocols belongs to?
Rip and BGP is in Application layer Ospf is in Transport Layer
What is the main difference between OSPF and RIP?
Both uses Distance vector algorithm...... . updates the routing table for every 30 seconds. and in OSPF requires hoping reneval of routing table
Compare and contrast human and mink anatomy?
Mink have much larger stomachs because they take big bites of their food. They have sharper teeth to rip thru skin.
What are most common dynamic routing protocols?
Dynamic routing protocols are "languages" routers use to communicate the details and status of networks to which they are connected. Examples include RIP, OSPF, EIGRP, BGP and IS-IS.They are called dynamic because they can respond to network changes, such as a failed link, a new link or in some cases a change to a link (perhaps a changed bandwidth value). This is in contrast to a static route, which an administrator must type in manually and which cannot automatically respond to network changes.Two routers must be running the same routing protocol to exchange route information; RIP cannot talk directly to OSPF, for example. The router admin must enable the routing protocol, then instruct the router which of its connected networks it should advertise to other routers running the same protocol.
Non-vendor specific routing protocols?
RIP and OSpf are non-proprietary protocoleigrp is a proprietary protocol i.e it is a vendor specific
