monitoring question - do we break this out in cacti?

There is not a simple way that our normal SNMP tools will reveal this. What we have are interface statistics for each of the networks/VLANs which terminate on the routers. We also have rules configured on the routers which are supposed to count IPv6 in/out packets & bytes on the external facing links. Since the inside-facing IPv6-only router interface is not configured to do IPv4, it is not likely to be contributing to IPv4 traffic. I can't be sure that the "firewall rules" on the external links are counting what they are supposed to be counting. What does seem inconsistent is the suspiciously low traffic counts on the v6-Only VLAN vs. the counts on the external link. I will look into this further. This will be made somewhat more complicated since we changed from our old firewall rules to RPKI-driven rules.

OK, thanks for checking and for the feedback.

I ask because of a discussion in sunset4: what kind of IPv4 traffic is generated on a link with no IPv4 service (as indicated by no DHCPv4 server responses)?  Seemed like ietf-v6ONLY might be a good place to take some measurements.
