[j-nsp] BGP: Prepending AS number

Hey everyone. New to Juniper and this list. My background is in Cisco/ 
Foundry so I am trying to get the hang of JunOS.

I have a working BGP peer with MCI, but I want to  prepend my AS  
number to make this link less preferred. As I said, right now, the  
peer is working fine, I just can't see the prepended AS number from  
public route servers.

BGP "group":

group MCI {
             type external;
             import martian-route-filter;
             authentication-key "$9$AauCtBElKW-dsvWJGiHTQIEcrWL"; ##  
SECRET-DATA
             export adv-filter-->MCI;
             peer-as 701;
             neighbor 157.130.247.5;
         }

and here is the adv-filter-->MCI policy statement:

policy-statement adv-filter-->MCI {
         term adv-networks {
             from {
                 protocol [ ospf bgp ];
                 route-filter 198.32.64.0/24 exact;
                 route-filter 192.0.32.0/21 exact;
             }
             then {
                 as-path-prepend "26711 26711";
                 accept;
             }
         }
         term reject-others {
             then reject;
         }
     }


I cleared the neighbor session, both soft and hard bounced it.

Is there anything else I am missing? According to the docs I found  
this should work just fine.

This is an M7i, running JunOS 6.4 (6.4R1.6)

Let me know if you need any other info.

Thanks!

Peter
