Ma napadlo ze uvediem priklad na ucenie z cisca. Test sa pise za kazdy celok, ktory sa sklada z dvoch az troch "lessons" z ktorych kazda lesson ma 6-12 podlekcii. Aby ste si vedeli predstavit rozsah uciva tak pridavam text z tretieho semestra z jednej podlekcie.
2.2
Single-Area OSPF Concepts
2.2.2
OSPF terminology
This page will introduce some terms that are related to OSPF.
Link-state routers identify neighboring routers and then communicate with the identified neighbors. OSPF has its own terminology. The new terms are shown in Figure .
OSPF gathers information from neighbor routers about the link status of each OSPF router. This information is flooded to all its neighbors. An OSPF router advertises its own link-states and passes on received link-states.
The routers process the information about link-states and build a link-state database. Every router in the OSPF area will have the same link-state database. Therefore, every router has the same information about the state of the links and the neighbors of every other router.
Each router then applies the SPF algorithm on its own copy of the database. This calculation determines the best route to a destination. The SPF algorithm adds up the cost, which is a value that is usually based on bandwidth. The lowest cost path is added to the routing table, which is also known as the forwarding database.
Each router keeps a list of adjacent neighbors, called the adjacency database. The adjacency database is a list of all the neighbor routers to which a router has established bidirectional communication. This is unique to each router.
To reduce the number of exchanges of routing information among several neighbors on the same network, OSPF routers elect a designated router (DR) and a backup designated router (BDR) that serve as focal points for routing information exchange.
The Interactive Media Activity will teach students about OSPF terminology.
The next page will compare OSPF to distance vector protocols.
Takychto podlekcii sa treba naucit na jeden test 12 az 30
Takto vyzeraju ucebne materialy, ktore dostanete na CD
EDIT : Jeden semester ma takych 10 testov.
... ak si este spomenies nahodou... co ste brali uplne na zaciatku?
