Tunnel MPLS + TE (Problema)
Publicado por Carlos (1 intervención) el 16/08/2017 15:56:23
Hola buen día estimada comunidad.
Espero puedan ayudarme con lo siguiente: % Only valid in Label Switching mode
** Problemas Tunnel **
Necesito implementar un Tunnel MPLS de manera dinámmica desde Cagua hacia el
Host 6.6.6.253
Previamente, he configurado paso a paso todos lo necesario.
Interfaces
OSPF (Multiárea como se muestra en la topología)
MPLS (Activo junto a MPLS + TE para soporte de Ingeniería de Tráfico)
LDP-IGP (Para Sincronizar LDP con OSPF)
RSVP (Reservando el Ancho de Banda Deseado)
Tunnels
El diseño ha sido probado gradualmente, a medida que se va configurando cada uno
de los puntos anteriores.
* Al iniciar el Router tenemos:
