Continuando con la senda del valor de MTU, un protocolo que nos indica este valor en un camino es EIGRP (protocolo propietario de Cisco, por ende no existe RFC asociado).
Seteamos eigrp en el AS 1 (Sistema autónnomo 1) compuesto por P1R1, P1R2 Y P1R4. Si sólo se modifica la MTU para los paquetes IP en la interface FastEthernet0/0 de P1R2 a 1498 bytes, en P1R1 la loopback del P1R4 se verá como sigue.
