        Al margen de que no todas las topologías son iguales puedo decir
      (luego de usar EIGRP por muchos años y en varias redes) que en lo
      personal tuve una experiencia MUY buena, todo andaba, poco
      mantenimiento e incluso manejando balanceo entre diferentes
      enlaces donde las métricas eran diferentes. Tuve que hacer
      balanceos entre WANs de diferentes ancho de banda, con MTU
      diferentes, con delays diferentes (terrestre y satelite)...,
      honestamente todo andaba perfecto, ahh, y una red de una red en el
      orden de los cientos de POPs.  <br>
        Si.., ciertamente todo Cisco.<br>
