As far as I know, proxy-arp is disabled under junos by default. Our peering at APE is done with M-series kit, and we didn't notice any issues.
I wasn't suggesting that the Junipers were proxy-arping, rather that when the Juniper gets two replies to an ARP broadcast it previously sent (one from the legit MAC, and one from the proxy-arping MAC), it seems to be a bit of a lottery which one the Juniper uses. I'm not sure if that means that other machines didn't see the proxy-arp, or if it's because other OS's seem to make more enthusiastic use of unicast ARP, or ignore the proxy-arper if the legit MAC keeps replying. But it is somewhat supicious that the only machines that lost route servers while this was happening were Junipers. Cheers Si
