[lacnog] Modelo de intercambio de IPv6 & IPv4 en un IXP

[Arturo Servin]

	I suppose monitoring could be one. If you have two interfaces you may get the data just by SNMP without netflow.

	Another could be that resiliency. Imagine that you have a flood DDoS on v4, then your v6 interface is unaffected (unless you hace CPU or other common resource affected).
