Hi muthu
R2(config-router)aggregate-address 171.1.0.0 255.255.0.0 summary-only
neighbor < R3-ipaadrees> unsuppress-map
Unsuppress
route-map Unsupress permit 10
match ip address 1
access-list 1 permit 171.1.0.0 0.0.255.255
I hope that will work
Thanks
Abdul

Subject: BGP aggregation
Hi team,
I have a scenario like this
R1(AS-100 )--------------R2(AS-300 )------------------------R3(AS-400)
.
.
.
.
.
R4(500)
R1 in AS 100
R3 in AS 400
R4 in AS 500
R2 in AS 300
All these three routers have EBGP peering with R2 which is in AS 300
R4 is advertising two routes 171.1.2.0 and 171.1.3.0
The requirement is R1 should see these routes as summarised form ie :
171.1.0.0
whereas R3 should see both the routes without summarisation.
if we use " bgp aggregate address 171.1.0.0 mask 255.255.0.0 summary-only"
in
r2, both R1 and R3 get aggregate routes.
So that is not the correct way. It looks like aggregate address to
specified
with respect to neighbor. But I am unable to use
above command to a specific neighbor.
Any help will be greatly appreciated
Thanks
Muthu
