Quick dumb question on S/RTBH. I get all the foo around the dynamic nature of using BGP to inject the bad prefix (source or dest) we want to drop.
At present we do this with destination dropping / blackholing. I want to drop RFC 1918 sourced packets coming to me at my edge towards providers / peers. I've got one provider sending me nearly 80Mb/s worth traffic with the source IP being in Net-10. Their answer is for me to ACL it. ICK My thought was to enable loose uRPF on the interface and create a static route for net-10 pointing to null0 interface te4/1 ip verify unicast source reachable-via any ip route 10.0.0.0 255.0.0.0 null0 shouldn't that cause net-10 into the FIB with a ptr to null0 and thus uRPF will discard ?? Netflow still shows traffic on that interface with source's in Net-10. I'm either brain dead, my sup720-3cxl is, or ??? thanks _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
