Configurando EIGRP IPv4/IPv6
Requerimientos
- En esta topología existen algunas configuraciones de EIGRP realizadas por un especialista, lamentablemente no funcionan de forma correcta, por lo cual su labor será la detección, corrección para el funcionamiento respectivo.
- Habilitar EIGRP en IPv4 de la forma más exacta posible, además de implementar router-id con formato “X.X.X.X” donde “X” representa el número del router. No olvide configurar interfaces pasivas según corresponda.
- Habilitar EIGRP en IPv6 a nivel de interfaces, además de configurar router-id con formato “XX.XX.XX.XX” donde “X” representa el número del router. No olvide configurar interfaces pasivas según corresponda.
- Garantizar salida hacia Internet en IPv4/IPv6.
- R1 deberá mandar de forma sumarizada las rutas a R2 a nivel de IPv4/IPv6.
- Deberá redistribuir entre AS de EIGRP en IPv4/IPv6. Utilizar los valores que contiene las interfaces como parámetros K.
- Generar un balanceo de carga donde el tráfico que proviene desde la loopback hacia el ISP y viceversa sea balanceada su carga, utilizando los routers R2 y R4 además de utilizar R3, a nivel de IPv4/IPv6.
- A nivel de IPv4, deberá solo utilizar los primeros 4 parámetros K para el cálculo de métrica.
- A nivel de IPv6, modificar temporizadores, dejando a 3 segundos los mensajes hello y 9 segundos el hold-time.
- Comprobar conectividad completa en la topología.
