Hi,
I have a Cisco ASR 9010 Router and I want to configure BGP BlackHole.
I want to know about the syntax that is needed to be applied in order to do this, because I am having some issues regarding BH application in IOS XR.
Lets say that I want to apply this to my Upstream with a blackhole community of 3257:666.
Lets suppose my blackhole community will be 65538:666.
route-policy BH
if community matches-any (65538:666) then
set community (3257:666) additive
endif
end-policy
So, this matches my community with the community of my upstream.
What else is needed to complete the configuration?
So, if I need to advertise to my upstream my IP 10.10.10.10/32, what should i do?
Regards,
Aridy

Hi Arian,
Here's a good document on how to use Remotely Triggered Black Hole (RTBH) on IOS-XR.

Hi Harold,
Thank you for the reply.
I have seen this material before, but I couldn't apply successfully the configuration on my router.
