Hi list,
I'm seeing blackholing on my inbound traffic from XO and their
downstreams (notably CNN) via Cogent. Prepending towards Cogent changes
my inbound path from 2828 174 39029 to 2828 3549 3292 39029 and it
works fine, even though the outbound path is still via Cogent:

IT depends on the manufacturer. Cisco can updates OIDs even on 1 second time
basis (maybe less?).
