Hi Sir/Ma'am,
Hope someone can help me... My problem is that I added new ip block to my bgp to advertise. I have to cisco routers by the way... Both have same configuration but the other one is not advertising my newly added ip block...
I did use "prefix list" and "suppress-map" on my config...
if you need my config please tell me should i put here... Thank you in advance
Solved! Go to Solution.

Why is it that this did not work?
neighbor 103.16.17.209 prefix-list FiberSpecific-Radius out
ip prefix-list FiberSpecific-Radius description Prefix Advertise to Radius
ip prefix-list FiberSpecific-Radius seq 100 permit 0.0.0.0/0 le 32

Hi ,
if you look at below output along with AS Path Filter list & Prefix List , you have also route-map for AS Prepend . On Route-map you don't have matching statement .
There by you have implicit withdrawn of 12 routes
Implicit Withdraw: 12 1771630
to match it i have given above configuration
Inbound path policy configured
Outbound path policy configured
Outgoing update prefix filter list is FiberSpecific-Radius
Incoming update AS path filter list is 55
Outgoing update AS path filter list is 10
Route map for incoming advertisements is RadiusLocalPref
Route map for outgoing advertisements is RadiusPathPrepend

A. Use these commands in order to check if the IP blocks are announced to the directly connected ISP:
The show ip bgp neighbors [address] advertised-routes command shows which messages are being sent.
The show ip bgp neighbors [address] routes command shows which messages are being received.
Note: The show ip bgp neighbors [address] advertise-routes command does not take into account any outbound policies you might have applied. In future Cisco IOS software releases, the command output will be changed to reflect the outbound policies. If there are two alternate paths to a destination, BGP always uses the best route to advertise.
