Router mitigation setup
Router mitigation requires a mitigation router that can distribute static routes on the network. You can use more than one mitigation router and specify different mitigation routers to cover different ranges of IP addresses.
To be fully functional, the router mitigation feature requires routers on the network to use unicast Reverse Path Forwarding (uRPF). It does not require that all routers use uRPF. However, enabling uRPF on more routers makes mitigation more effective. Also, uRPF-enabled routers near the edge of the protected network are generally more effective than uRPF-enabled routers in the core of the network.
Mitigation routers are specified on the Administration > Mitigation > Routing Setup pages.
