Multi-router single AS BGP issue

CiscoPurpleBelt

Attached is a pic of my lab topology (the 230. is a typo is it 203 as in config) - I am only concerned with the AS 65000 which is circled.

So Routers R11, R16, and R5 can all talk to each other (R11 is the RR) but R15 can't ping anything on R16 and R5 or beyond 0 - and vice versa, all other routes can ping everything in entire topology. I believe I don't have something configured properly see -below.

 

 

R11#sh running-config | section bgp
router bgp 65000
bgp router-id 11.11.11.11
bgp log-neighbor-changes
network 11.11.11.11 mask 255.255.255.255
network 50.1.1.4 mask 255.255.255.252
network 100.1.1.1 mask 255.255.255.255
network 203.3.3.0 mask 255.255.255.252
network 204.4.4.0
neighbor 50.1.1.6 remote-as 65000
neighbor 50.1.1.6 route-reflector-client
neighbor 203.3.3.1 remote-as 65000
neighbor 203.3.3.1 route-reflector-client
neighbor 203.4.4.2 remote-as 65000

Solving it myself the "network 204.4.4.0" on R15 was a typo. Change it to 203.4.4.0 and everything was pingable.
