Un problema de aprendizaje de MAC del switch Huawei causó que quede
afuara la MAC del router de peering con la IP 200.115.81.254.
Les mando lo que se vió:

Haciendo shutdown de los dos lados switch y router y después de un rato
volviendo a levantar con no shutdown/undo shutdown no cambia nada y
sigue igual. Incluso desconectar, esperar un rato y conectar el cable
tampoco.
En los logs del switch no aparece nada raro
y en los del router solo la alarma del FAN.
