Cisco ASR 9K Route polices

[mspdog22]

Hello 

We have several links to different IXP's in the region and also BGP sessions with several upstream providers. What i am trying to do is if any ASN is located in any of the IX that we peer with we then want to remove the routes that we get from our up stream providers. 

We are looking to do this to limit the number of routes we are putting on the router. 

Would this be possible?

How big is this may be considered RR part of the design again; this needs to be tested and role across where you are looking to do

My view as below :

I dont full understand issue here

But from what I get you need 

Rpl to match as-path abd deny prefix 

Am I correct?

here is a simple example if still needed

## create as path match

!
as-path-set TESTING
passes-through '12345'
end-set

## route-policy

!
route-policy BGP_OUT
if as-path in TESTING then
drop
else
pass
endif
end-policy
