You don't have prefix-list test applied inbound from R1. R3
needs to say "neighbor 20.20.20.1 prefix-list test in" under the ipv4
unicast address-family.

Subject: BGP ORF Capability
Hi,
I have issues with ORF. I may be misunderstood it.
This is the setup I have
R3 - 20.20.20.3 <----------> 20.20.20.1 - R1
It is an ebgp peer. I am advertising 3 routes from R1 to R3 via BGP. I
would like to configure ORF to filter two of the three routes and allow
only 1.1.1.0/24. Please check the configuration and let me know what I
am doing wrong?
R3
