Isn't that what a routing loop is, when it loops back out to the transit/interface from which it entered? Paul On Fri, Jul 18, 2008 at 7:07 PM, <Guy_Shields@stream.com> wrote:
This is not a routing loop. It is simply a route that was not tied down via a static route to NULL with a weight of 254.

I'd like to rip on Mzima as much as the next guy, but I'm not sure how they could "fix" this routing loop, shy of some creative ACLs.
You should try contacting Ubiquity, as this traceroute looks like an issue on their (Mzima's customer's) side.
