Parse cisco's "show ip route" output in Python 2.7

I've done little with Ciscos,  but what if you use individual things like
 "show ip ospf", "show ip rip database", etc. instead of "show ip route".
Does that makes things a little more consistent?

Often big problems are simpler if we can divide them into smaller, more
manageable subproblems.
