Maybe I misinterpreted the question, but het, that's never stopped me before :) The 'network' statement on the routing protocol doesn't necessarily specify the EXACT netblock to announce. The 'network' statement merely gives you what range of netblocks to announce, or establish neighbor adjacencies on. So a 'network 150.50.25.2' statement says to establish neighbor adjacencies with anything 150.50.0.0 range (150.x.x.x is in the class 'B' range, so by default has a /16 netmask unless you tell it different), and announce any connected interfaces that are in the 150.50.0.0/16 range. Personally in production I purposely restrict down the network statements to the smallest possible, but that's only so I know it's a 100% conscious decision that I'm injecting a route into the production route tables :) Make sense?
