On R2 specify an inbound route-map like
route-map nontransit
set community no-export
Then apply it for EBGP peers
neigh x.x.x.x route-nap nontransit in

Hi Guyes
I have following setup
AS1 AS2 AS3
192.1682.2.3/24r1------------r2--------------r3-172.16.2.3/24
ebgp ebgp
I am trying to make AS2 a non-transit AS. I can achieve this by using
following config at r1 so that r1 passes only locally generated networks to
AS1 and AS3. But if I want to achieve the same result without using AS path
access list .how can I do that? Any help on this will be appreciated.
!
router bgp 1
bgp router-id 139.16.1.1
neighbor 139.16.12.2 remote-as 5
neighbor 139.16.12.2 route-map localonly out
neighbor 139.16.25.2 remote-as 2
neighbor 139.16.25.2 route-map localonly out
no auto-summary

route-map localonly permit 10
match as-path 10
!
ip as-path access-list 10 permit ^$
