Hi,
While making some changes to the routing table on one of our routers
today I noticed that "route add" was showing some strange behaviour.
When adding a route for 128/8 to the table rather than adding
128.0.0.0/8 it would add 0.0.0.0/8, however adding 10/9 works correctly.
Is this a bug in route or the routing table?
