Hi, I am trying to set up a static route to blackhole, but the next hop is unreachable: Here are the route I am trying to push (notice I have tried blackhole and Null0): ip route 192.0.2.1/32 blackhole ip route 192.0.2.2/32 Null0 But the routers keep saying the next hop is unreachable: show ip route static Codes: K - kernel route, C - connected, S - static, R - RIP, O - OSPF, I - IS-IS, B - BGP, E - EIGRP, N - NHRP, T - Table, v - VNC, V - VNC-Direct, A - Babel, D - SHARP, F - PBR, f - OpenFabric, > - selected route, * - FIB route, q - queued, r - rejected, b - backup S>* 192.0.2.1/32 [1/0] unreachable (blackhole), weight 1, 00:07:48 S>* 192.0.2.2/32 [1/0] unreachable (blackhole), weight 1, 00:08:15 show ip route 192.0.2.1/32 Routing entry for 192.0.2.1/32 Known via "static", distance 1, metric 0, best Last update 00:08:23 ago * unreachable (blackhole), weight 1 I need this to work in order to set up RTBH (null route the next hop). On a Cisco router, the same configuration show a directly connected route : show ip route 192.0.2.1 Routing entry for 192.0.2.1/32 Known via "static", distance 1, metric 0 (connected) Routing Descriptor Blocks: * directly connected, via Null0 Route metric is 0, traffic share count is 1 Thank you Regards
