My Cisco 6509s/7204s/3550/3560/linux boxes support it just fine (philosophy aside, it *works* over ethernet, even in a test case when 'PtP' really meant 'these are the only two ports in the VLAN'). Anything I own with an ARM chip (Mikrotik, Ubiquiti, or general embedded hardware) in it, and my PFsense boxen, don't support it at all. Very sad - some days, it almost makes me want to roll a bunch of iptables boxes and reclaim a ton of usable IP space. Almost. :) Anyways, didn't mean to hijack the OP! Interested to see if Comcast is actually handing him a /29, or just 5 IPs out of a bigger subnet, and if they'll route that /29 to him.
