Implementacion de Prefix-List y Route-Map

Requerimientos

  • Habilitar EIGRP según AS propuesto y OSPFv2 de forma clásica. Dejar interfaces pasivas donde sea necesario.
  • Considerar para R4, que las loopback en IPv4 deben ser enrutadas para EIGRP y para IPv6 enrutadas en OSPF.
  • Deberá realizar redistribución entre protocolos de enrutamiento a nivel IPv4 mediante route-maps, pero deberán existir las siguientes consideraciones:
  • A. Las rutas que provienen de EIGRP hacia OSPF deberán tener una métrica variable en su resultado final, pero al momento de pasar por el router de borde le deberá añadir una métrica de 60.
  • B. Las rutas que provienen OSPF hacia EIGRP deberán ser redistribuida, obteniendo los parámetros K de interfaz correspondiente.
  • La redistribución entre OSPF y EIGRP para IPv6 será de forma directa.
  • Loopback 2 no debe ser vista por el router R1 a nivel IPv4.
  • Loopback de R5 debe ser vista solo por el router R5 a nivel de IPv4.
  • Router R6 no debe ver las loopback 5 ni loopback 555 a nivel de IPv6.
  • Router R4 deberá permitir solo rutas a nivel IPv4 con prefijos entre el /24 y el /26.
  • Comprobar conectividad completa en la topología.
