Comandos relacionados a RIP
RouterRip(config)# router rip
RouterRip(config-router)#network XX.XX.XX.XX (máscara por defecto, o asume la configurada en la interfaz)
RouterRip(config-router)#version 2 (activa versión 2 si es necesario)
RouterRip(config-router)#redistribute static (propaga rutas estáticas dentro de RIP con metrica 1)
RouterRip(config-router)#redistribute static metric
5 (con una metrica distinta a 1)
RouterRip(config-router)#distance ? (distancia adminsitrativa, por defecto 120)
<1-255>
Administrative distance
RouterRip(config-router)#timers ? (para variar valores por defecto de los temporizadores)
basic Basic routing protocol update timers
RouterRip(config-router)#timers basic ?
<0-4294967295> Interval
between updates
RouterRip(config-router)#timers basic 20 ? (actualizaciones de la tabla, default 30 segundos)

DECLARAR INTERFACES PASIVAS:
RouterRip(config-router)#passive-interface
INTERFACE (no transmite publicaciones, pero participa
en RIP)
CANTIDAD DE RUTAS PARA EL BALANCE DE CARGA:
RouterRip(config-router)#maximum-paths 6 (las rutas deben tener costos iguales (misma cantidad de
saltos))
EQUILIBRADO DE CARGA POR PAQUETE:
RouterRip(Config)#int s0/0 (si
ambas interfaces alcanzan la ruta x.x.x.x)
RouterRip(config-if)#no ip route-cache (un paquete por cada interfaz (uno y uno o Round Robin))
RouterRip(Config)#int s0/1
RouterRip(config-if)#no ip route-cache
EQUILIBRADO DE CARGA POR DESTINO:
RouterRip(Config)#int s0/0 (si
ambas interfaces alcanzan la ruta x.x.x.x)
RouterRip(config-if)#ip route-cache (sesión con host remoto x.x.x.A por esta interfaz)
RouterRip(Config)#int s0/1
RouterRip(config-if)#ip route-cache (sesión con host remoto x.x.x.B por esta interfaz)
DESABILITAR HORIZONTE DIVIDIDO:
RouterRip(Config)#int s0/0
RouterRip(config-if)#no ip split-horizon
PARA CONFIGURAR RIP DISPARADO POR EVENTOS:
RouterRip(Config)#int s0/0 (sólo
en interfaces serial)
RouterRip(config-if)#ip rip triggered
VERIFICACION DE LA CONFIGURACION:
RouterRip#sh ip
protocols (verificación de temporizadores)
