Hi Tarun.
Thanks for the response.
This example specifically talsk about aggregates and suppress-maps.. I have
seen something "weird" with an unsupress map in combination with an outbound
route-map as a prefix filter..
specifically
if i have on R1
router bgp 100
aggregate address 1.0.0.0 255.0.0.0 summary-only
nei 1.1.1.2 unsuppress-map UNSUPRESS
nei 1.1.1.2 route-map TO-R2 out
route-map UNSUPRESS permit 10
route-map TO-R2 deny 10
match ip address prefix VLAN3
route-map TO-R2 permit 100
ip prefix-list VLAN3 permit 1.1.3.0/24
i am still seeing 1.1.3.0/24 appear on R2 ??
so it seems that the route-map is over-riden by the supress map...
How i got around it was to add the "deny vlan3" configuration to the
unsupress map
...
which made the UNSUPRESS route map look like
route-map UNSUPRESS deny 5
match ip add pref VLAN3
route-map UNSUPRESS permit 100
