Hi, i need to advertise 172.20.224.0/22 to EBGP neighbor if i receive all of the following
172.20.224.0/24
172.20.225.0/24
172.20.226.0/24
172.20.227.0/24
But Problem is even if one is received in IF EXIST, Advertise MAP will advertise /22 .
i want it to advertise only if all 4 Routes are present.
How can i achieve this AND condition?
METHOD 1 Failed.
rotuer bgp 65333
neighbor 192.168.12.1 advertise-map ADVERTSIE-ROUTE exist-map IF-RECEIVED
route-map IF-RECEIVED, permit, sequence 10
Match clauses:
ip address prefix-lists: IF-RECEIVED

MRTHOD 2 Failed.
Alternately i tried to adveritse on basis on AS Number, all of above routes are learnt from AS number 65444 , but in this case nothing gets advertised at all to neighbor.
route-map IF-AS-REC, permit, sequence 10
Match clauses:
as-path (as-path filter): 209
ip as-path access-list 209 permit ^65444
neighbor 192.168.12.1 advertise-map ADVERTSIE-ROUTE exist-map IF-AS-REC
