Estimados,<br>
<br>
El día sábado 16/5 se reportó un evento en el IXP MZA.<br>
En primer momento se perdió gestón y monitoreo desde RCN por lo que
se generó el ticket TT2912 y se reclamó por el enlace a Silica.<br>
<br>
<img src="cid:part1.52AE0D08.29BE88C7@cabase.org.ar" alt=""><br>
<br>
Recibimos en ese horario un pico de 85 kpps L2 Multicast en RCN
proveniente de MZA.<br>

<br>
Al ser L2 no quedaron registrados en nuestro sistema de análisis de
tráfico.<br>
<br>
Durante el evento pudimos ver una gran cantidad de paquetes ICMPv6 y
la caída de las sesiones BGP en AF IPv6 tanto de MZA-ROU03 como en
RCN.<br>
Y tambien la caída de sesiones BGP AF IPv4 en MZA-ROU-01<br>

Conclusion:<br>
<br>
El miembro FDJ inyectó una cantidad extraordinaria de paquetes
Broadcast y Multicast.<br>
Los paqutes de Broadcast fueron mitigados por la configuración de
storm-control existente en la interface.<br>
Los paquetes de Multicast se propagaron a todos los enlaces del IXP
MZA incluyendo el de RCN.<br>
El procesamiento de dichos paquetes afectó al MZA-ROU-03 y
RCN-ROU-05, ambos Force10 Exascale.<br>
El filtrado de paquetes Multicast no está soportado por las
tecnologías actuales del IXP MZA.<br>
<br>
<br>
Problemas encontrados que requieren atención:<br>
Bajar administrativamente las interfaces que no están cursando
tráfico.<br>
Configurar los Etherchannel en LACP. Ya que una mala configuración
del lado de los miembros podría generar un loop.<br>
