I have a certain use case with rtbh for the following:

  1. A /32 route (say is injected into the network with a specific bgp community
  2. I’d like to match the aggregate prefix that /32 belongs to (say and attach the “no_advertise” community to it or simply stop advertising it to our peer.

Is this even possible on junos or ios-xr? I’ve been trying to figure it out with policy statements in either case but to no avail.

If possible, if someone can provide config snippet examples, it’d be very helpful.

Thank you
