[quagga-users 14915] Re: Setting a BGP daemon to advertise received router from its neighbors to other neighbors in Quagga

Hi,

Thank you William, but I can not understand your email at all!

Here is the content of my AS which I want announce the routers received 
from its customer:

AS 9 is AS 7's customer and AS 4 is AS 7's provider:

!neighbor 9
neighbor 1.9.0.1	remote-as 9
neighbor 1.9.0.1	port 20028
neighbor 1.9.0.1	update-source 1.7.0.1
!customer (full routes)
neighbor 1.9.0.1	route-map RMAP_CUSTFULL_IN in
neighbor 1.9.0.1	route-map RMAP_CUSTFULL_OUT out


!Policy
!
!community values:
!  customer    : 100:30
!  non-customer: 100:20

!localpref values:
!  customer: 30
!  peer    : 20
!  provider: 10

!Route attributes for locally originated prefixes
!community values: 200:<numeric-attr>

route-map RMAP_PROV_IN permit 10
   set community additive 100:20
   set local-preference 10
route-map RMAP_NONCUST_OUT deny 10
   match community NONCUST
route-map RMAP_NONCUST_OUT permit 20
   match community CUST

! should never reach this actually
route-map RMAP_NONCUST_OUT permit 30

route-map RMAP_CUSTFULL_IN permit 10
   set community additive 100:30
   set local-preference 30

route-map RMAP_CUSTFULL_OUT permit 10


ip community-list standard CUST permit 100:30
ip community-list standard NONCUST permit 100:20
ip community-list standard NONLOCAL permit 100:20
ip community-list standard NONLOCAL permit 100:30


But it does not work. AS 7 receives update message from AS 9, but it 
does not announce that to AS4!!

Best,
Shahrooz
