No es nada bueno, pero tiene soluci\u00f3n:<\/h1>\n

Si por alguna raz\u00f3n estas configurando tus equipos routerboard, puede que en alg\u00fan punto necesites acelerar el proceso de configuraci\u00f3n y decidas crear\u00a0un backup de uno de los equipos para luego restaurarlo en el resto de los los routerboard que vayas utilizando.\u00a0El problema oculto sobre esto es que \u00abTe\u00a0clona los MAC-Address del primer equipo al que le hiciste el backup\u00bb<\/strong>. Y eso para equipos que pertenecen al mismo segmento de red,\u00a0cr\u00e9eme\u00a0que no es nada bueno<\/span><\/em>.<\/p>\n

Ya me hab\u00eda pasado antes que me aparec\u00eda eventualmente un mensaje en los logs que decia algo como:\u00a0received<\/span> packet<\/span> with<\/span> own<\/span> address<\/span> as<\/span> source<\/span> address. <\/span><\/span><\/strong>Y por supuesto, tal y como siempre sucede, \u00abEn el momento del problema, nunca aparece la soluci\u00f3n\u00bb.<\/span><\/span>
\n<\/span><\/span><\/strong><\/p>\n

Hace una semana, arme un PHP para\u00a0poder serializar la configuraci\u00f3n de muchos\u00a0routerboard. Mi problema puntual: No conectaba el VPLS y ademas, volvi\u00f3 este bendito error en el log.<\/p>\n

Leyendo en forum.mikrotik.com<\/a> encontr\u00e9 que la soluci\u00f3n es resetear los mac-address a\u00a0su direcci\u00f3n original. Asi que recuerda!! cada vez que restaures un Backup, ejecuta este comando.<\/p>\n

\r\n\/interface ethernet reset-mac-address 0,1,2,3,4,5,6,7,8,9,10\r\n<\/pre>\n
En este caso, es un RB2011\u00a0el cual trae 11 interfaces, 10 ethernet y 1 sfp. Por eso va del 0 al 10. Por ejemplo en un RB 750 (5 ethernet) el comando seria asi:<\/p>\n
\r\n\/interface ethernet reset-mac-address 0,1,2,3,4\r\n<\/pre>\n
Enjoy!!.<\/p>\n","protected":false},"excerpt":{"rendered":"
