we only want route in routing table so that BGP will advertise routes to it's neighbours. We can either create the blackhole route or we can create one loopback vlan and point all the static route to that loopback vlan as next-hop and change the metric value of static route as shown below..

create vlan test
config vlan test ipaddress 10.1.1.1
enable ipf

enable loopback-mode vlan test

configure iproute add 61.57.210.0/24 10.1.1.1 222

Awesome! Thank you, Gents. I am wondering why we need blakhole route for those subnet. Will it cause any problem?
