I also had the same problem. I'm running ios 12.1.10 on 2524 router. I
tried no sync, no auto-summary, but unsuccessful. Routes that are learned
from static, dynamic, or connected are not advertised using the network
statement? Has anyone else experience this?

Here is a basic BGP setup with r1 and r2:
r1 AS100 r2 AS200
s0----------------s0
lo0 1.1.1.1 lo0 2.2.2.2
I am advertising both r1's and r2's loopbacks lo0 by putting under a
network statement.
but somehow they never showed up in the other's BGP table. What am I doing
wrong?
here is the configs and output from both r1 and r2:
r1#
