ip routing preference problem

Last updated on January 24, 2024

        On my Huawei CE12800 device, I am trying to run this config. Beside a standart BGP process, I am using three community values to control traffic with my upstream provider. With 555 community value, I can block traffic which has an international origin. 10.20.30.3 should be reachable only from my local network and from upstream network. Despite of I can succesfully announce 10.20.30.3 with 555 community, but static ip route to NULL interface blocks the traffic. I need a ***** route entry to bring up BGP announce which doesn't block traffic locally. 

BTW, this setup works on my old 3com 8800 device.
