Unfortunately it's not the first time that:
1) someone with enable screwed up a routing design or did something dumb 
like dueling static routes, or some similar kind of rubbish.
2) someone with enable (or someone who manages peple with enable) co-opted 
arbitrary non-1918 IP space for use on their internal network.  Calling it 
RFC1919 space would almost be funny if it weren't such a pain the butt to 
deal with people who do things like this.
