CCNP Certification / BSCI Exam Tutorial: EIGRP Stuck-In-Active Routes

The success in the test & 39; OIOS and win your CCNP, all the details, and if it is & 39 d & 39; EIGRP SIA routes, there are many Details on. A quick review in a search engine to help " SIA & quot; opened a number of games. Troubleshooting SIA routes is very challengin was in & 39; n & 39; there is not only a reason & 39; they occur.
View EIGRP topology in the table with the show ip eigrp topology command, and you will see a code, in addition to the possible successor to the successor. A popular misconception is that we want these routes have & quot; A & quot; besides d & 39; them - are now active. That is what we want, or not? Active routes sound good, right?
Well, they sound good, but I am not. If a road show that Active EIGRP topology in the table, which means that the calculation of DUAL is currently on this path, and it is currently not used. When a street is & 39; passive (& quot; P), it means that this & 39; n is not recalculated, and it is used route.
Generally, Way showed that the Active will be there for a very short period of time that you repeat the command, which we hope & 39; itinerary actively and passively. Sometimes this is not done, however, and the road is SIA - Stuck In Active.
A route is SIA & 39; when a request is not answered is, as long as the relationship is zero. From experience I can say that you are troubleshooting SIA roads is an art, a science & 39, but there are four main reasons d & 39, a route is SIA:
The simplex link, so that the query can not be required answered.
The router resources are not available, usually due to the high CPU router utilization.
The asked the memory of the corruption or & 39; prevent the router to respond, the query.
The link between the two routers is of poor quality, was just enough packets through the relationship remains intact neighbour, but not sufficient for the correct answers through.
To summarize, the streets are normally SIA, when a neighbor or l &; 39; other is not responding to a question, or in the application or the reply has a bad curve somewhere. I have told you that this & 39; was not the best thing to do troubleshooting!
