I recently encountered a question about the number of RIP hops and the maximum number of routers contained in a link. I am also confused. Is it 15 or 16? I checked it on the Internet and found that many people cannot understand it like me, so I had to check the information myself.Huang Tianyan has no heart! Finally, we finally figured out that the maximum number of hops supported by RIP is 15. Because 15 or
Because RIP is usually a broadcast protocol, to update the RIP Router to a non-broadcast network, the Cisco IOS software should be set to allow route information exchange between the two. To do this, run the following command in vro configuration mode:
To control a group of interfaces and exchange router update information with them, you must set the passive interface command to in
According to the V-D algorithm, a route is refreshed only when a better route appears; otherwise, it is retained in the routing database. This ignores the situation that when a route suddenly crashes, you need to select a new route to replace the existing route. But it is not solved by refreshing algorithm in V-D.
In practice, RIP specifies that all machines set a clock for each table in the route database. Each time a new table is added, set a new c
In view of the characteristics of the dial-up network routing, it is impossible for us to regularly broadcast the routing on the dial-up network for 30 seconds, just like on the LAN and the leased line network, thus, we cannot process the timeout of the route on the dial-up network like the route on the LAN.
Based on this consideration, in order to ensure the timeliness and feasibility of the route, we stipulate that the route modification packet on the dial-up network should be sent in the foll
The offset list is used to obtain paths through RIP and increase the inbound and outbound distances. This is to provide a local mechanism to increase the routing selection scale value. You can also restrict the offset list for the access table or interface. To add a route selection scale value, run the following command in vro Setting Mode:

OSPF (Open Shortest Path First) is affiliated with IGP (Internal Gateway Protocol)Used for decision routing in a single autonomous system. It is an implementation of the link status routing protocol.

SummaryThe ease of configuration, flexibility, and ease of use of r I P makes it a very successful routing protocol. Since the development of r I P, it has made great strides in computing, networking and interconnection technologies. The accumulation effect of these advances makes r I P a popular protocol. In fact, many routing protocols in use today are more advanced than r I P. Although these protocols are successful, r I P is still a

Q: What is the difference between RIP, IGRP, and iversions?
A: There are different types of routing protocols. The main difference between RIP and IGRP is the distance vector protocol, while that between RIP and IGRP is the connection status protocol. The protocol running, time (such as update and refresh), and route table tracking are different.
