Valdis, you are correct. What your seeing is caused by multiple IP

Am I incorrect, though, in believing that ARP packets should only be visible
within a broadcast domain,
broadcast domain != subnet
It surprises me that in this day and age, in a forum like this that has
an active thread about kids being taught archaic concepts, we see
language like "broadcast domain != subnet" and a perceived need to
explain it.
[no longer germane material deleted to reduce excess baggage charges]
int ethernet 0/0
ip address 10.0.0.1 255.255.0.0
ip address 11.0.0.1 255.255.0.0 secondary
ip address 12.0.0.1 255.255.0.0 secondary
The broadcast domain will have ARP broadcasts for all three subnets.
This are not "subnets"! They are IP addresses in three different IP
networks.
Doing it over a CMTS doesn't change that.
Communication here perceived as hostile is apologized-for.
