8Classful routing protocols do not send masks in the routing update messages.

OSPF, and the other uses EIGRP, on at least one router, both OSPF and EIGRP must be used. Then,

that router can take routes learned by OSPF and advertise them into EIGRP, and vice versa, through a

process called route redistribution.

Si el router aprende rutas por diferentes protocolos de enrutamiento

to the same subnet, because each routing protocol’s metric is based on different information, IOS cannot compare the metrics.

Distancia administrative denota que tan credible es un protocol de enrutamiento entero en un solo router. El numero mas bajo, el major, o el protocol de enrutamiento mas creible .

For example, RIP has a default administrative distance of 120, OSPF uses a default

of 110, and EIGRP defaults to 90. When using OSPF and EIGRP, the router will believe the EIGRP

route instead of the OSPF route (at least by default).

link-state advertisement (LSA)

In OSPF, the name of the data structure that resides inside the LSDB and describes in detail the

various components in a network, including routers and links (subnets).

link-state database (LSDB) : en OSPF la estructura de datos en

In OSPF, the data structure in RAM of a router that holds the various LSAs, with the collective

LSAs representing the entire topology of the network.

Each LSA is a data structure with some specific information about the network

topology; the LSDB is simply the collection of all the LSAs known to a router.
