Yup. These are internet circuits which always have traffic on them, both
in and out. I even set up a 10 second ping using Netwatch as a
keep-alive. Didn't do shit. Could be a RouterOS bug. But I see this on
the ASE circuits and nowhere else like internal PTPs. So I don't get it.

If there is constant traffic from this IP/MAC pair, shouldn’t that
keep the ARP cache refreshed so no ARP requests are needed (after the
first one)?

ASE = AT&T Switched Ethernet. Comcast and others pretty much all do
the same shit for MetroE.
We have three ASE circuits at different locations. All are Ciena 3930s
with 1G optical hand-off direct to our routers. Each has a different
peer at the other end of the EVC.
I would get a complete halt in traffic for 2-3 seconds. It was easy to
catch while running a fast ping interval (50-100ms). I'd see "no route
to host" exactly when the traffic would quit. We were getting no ARP
replies. Like an ARP or broadcast rate limiter or filter was
mysteriously turned on. So I made the ARP entries for the upstream
peer static and didn't have any more problems.
I've had this problem on all three from time to time, lasting for
minutes, hours or days and then it just vanishes. Even had two
circuits doing this simultaneously. So I don't know if it's the 3930s
or the ASE core network. Although it has been a few months since I've
seen it.
I couldn't say if this is your problem, just wanted to give my
experience because it sounds so similar.

Att MIS not Ase, involves also another carriers "ase" product (not
at&t) but since all traffic through both peers goes to zero I'm
assuming it's elsewhere?

Stupid question. Does this involve AT&T ASE at all?

I have 2 peers, one CCR and 2 backhauls connected to a 10G

the 10G switch everything functioned normally (had a

traffic my traffic will go from 1500mbps to 0mbps for just
a instant then back to 1500mbps, other times it goes from
1500mbps to 750mbps and back to 1500. Sometimes it happens
30 times a minute sometimes 2 times per hour.
I've swapped the switch, sfp's...
Anyone with any remotely plausible idea would be greatly
appreciated
