Tipos de direcciones IP multicast

Posted on Actualizado enn

Hola en esta entrada quiero hablar de lasdirecciones multicast.

No entraré en IPv6 porque ya lo he escrito en esta entrada

Las direcciones multicast en IPv4 vienen definidas en el rfc3171

IANA Guidelines for IPv4 Multicast Address Assignments

224.0.0.0 – 224.0.0.255 (224.0.0/24) Local Network Control Block
224.0.1.0 – 224.0.1.255 (224.0.1/24) Internetwork Control Block
224.0.2.0 – 224.0.255.0 AD-HOC Block
224.1.0.0 – 224.1.255.255 (224.1/16) ST Multicast Groups
224.2.0.0 – 224.2.255.255 (224.2/16) SDP/SAP Block
224.252.0.0 – 224.255.255.255 DIS Transient Block
225.0.0.0 – 231.255.255.255 RESERVED
232.0.0.0 – 232.255.255.255 (232/8) Source Specific Multicast
Block
233.0.0.0 – 233.255.255.255 (233/8) GLOP Block
234.0.0.0 – 238.255.255.255 RESERVED
239.0.0.0 – 239.255.255.255 (239/8) Administratively Scoped Block

En el rango 224.0.0.0 – 224.0.0.255 (224.0.0/24) se conceden la IP’s segun la siguiente tabla, creo que las importantes para el CCNA son las siguientes

224.0.0.2 All Routers on this Subnet

224.0.0.5 OSPF descurimiento en la red

224.0.0.6 OSPFIGP Comunicacion entre routers adyacentes

224.0.0.9 RIP2 Routers

224.0.0.10  EIGRP Routers
