Hi Yu
Many thanks for your input, that is exactly what was needed.
My config for those that are interested.
router bgp 500
aggregate-address 1.1.0.0 255.255.0.0 suppress-map suppress
ip prefix-list letsum seq 5 permit 1.1.0.0/16 ge 17
route-map suppress permit 10
match ip address prefix-list letsum
As per Parkhurst.
This has the benefit of filtering any other networks as well.
Many thanks
Larry
