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

The problem is that I do not know how I can define customer and
provider
relation ship in quagga bgp conf files. I confused by route-map
description.
If some can define just one simple customer provider relationship
between
just two nodes, I will be so appreciated.
Another router of yours which is not a customer or provider is the
same AS number.
A customer or provider is a different AS number.
BCP 38, you reject any routes not expected from the customer in the
prefix-list applied to the customer via a route map,
You also limit the routes offered to the provider to just yours and
the customers' using a prefix-list applied to the provider via a route
map.
