Hiya.

BGP will only advertise a route it has a non-default-route path to.  You have to have one route that encompasses the whole subnet, not three or four that add up to the whole thing..

Do a show ip route 203.149.64.0 255.255.240.0  If it comes back with route not in table, or it says the source of the route is bgp 17766, or the route in the table is 0.0.0.0/0, then add the following to your config.

ip route 203.149.64.0 255.255.240.0 null0

If that doesn't fix it, You can IM me and I'll be glad to help.

Ok - BGP session is established, successfully receiving routes, but not 
advertising.

I have the following:

!
router bgp 17766
 no synchronization
 bgp log-neighbor-changes
 bgp deterministic-med
 network 203.149.64.0 mask 255.255.240.0
<other neighbour statements removed>
 neighbor Connect_Open_Pipe peer-group
 neighbor Connect_Open_Pipe remote-as 2764
 neighbor Connect_Open_Pipe soft-reconfiguration inbound
 neighbor Connect_Open_Pipe distribute-list DEFAULT_ROUTE_IN in
 neighbor Connect_Open_Pipe route-map unlimited-traffic out
 neighbor 203.63.121.150 peer-group Connect_Open_Pipe
 no auto-summary
!
ip access-list standard DEFAULT_ROUTE_IN
 remark accepting from BGP peers
 permit any
!
!
route-map unlimited-traffic permit 10
 match ip address prefix-list unlimited-traffic-prefixes
 set ip next-hop 203.63.121.150
!
!
ip prefix-list unlimited-traffic-prefixes seq 10 permit 203.149.70.0/24
ip prefix-list unlimited-traffic-prefixes seq 100 deny 0.0.0.0/0 le 32
!

gc-rt-02#show ip bgp neighbors 203.63.121.150 advertised-routes 

gc-rt-02#

Any help is greatly appreciated!

Regards,
MB
