A BGP announcement problem

Lets say you have the config like below:

int loopback0
 ip add 10.1.1.1 255.0.0.0

ip route 100.100.100.0 255.255.255.0 null0
ip route 100.100.101.0 255.255.255.0 null0

And you want the above networks to be announced as follows:

10.0.0.0
100.100.100.0/24
100.100.101.0/24

I wanted to get this to work with using only a "network" statment for the
10.0.0.0 network, and just "redistribute" statment for the 100.100.10X.0
networks. But I can't seem to get this to work.

To get the 100.100.10X.0 networks to announce as /24's, I have to do
"no auto-summary". But when I do that, for whatever reason, my 10.0.0.0
network will no longer announce:

router bgp 1
  redistribute static
  network 10.0.0.0
  no auto-summary

I also tried:

router bgp 1
  redistribute static
  network 10.1.1.0
  no auto-summary

Any ideas? The rules I am trying to live by with this is:

1. the 10.x.x.x needs to announce as /8
2. the 100.100.10X.0 needs to announce as /24
3. use "network" statment on the 10.x.x.x network
4. use "redistribute" statment on the 100.100.10X.0 networks
