BGP Not Advertising Locally Connected Network

Hi All -

this is a very very simple set up of eBgp peering via loopbacks and then
advertising the local loopbacks. The idea is to get the candidate to
realize the recursive routing issue and to use the backdoor command for the
network statements. The problem is, my routers are not advertising the
loopbacks? Any ideas?
