[f-nsp] MLX and uRPF for RTBH

Hi All,

Wondering if anyone has used the uRPF feature on MLX to have the source
address of traffic matched to null0 routes?

My reading so far has lead me to a config like this:

reverse-path-check
urpf-exclude-default
!interface eth1/1
rpf-mode loose log

!


Example routes look like this:

device#sh ip route 2.144.0.0/24
        Destination        Gateway         Port          Cost          Type
Uptime src-vrf
1       2.144.0.0/24       DIRECT          drop          20/0          Be
3d1h   -

My next step is the lab.

Cheers
