RP Filter

RouterOS General
1

Hi All,

I’m implementing RP Filter on Routeros v6 and I’m looking for ways to debug it.

I know i can use firewall rules with logging, and use packet capture to see there really being sent.
But I want a easy way of debugging it.

On Cisco and Juniper gear I have counters where I can see its dropping pakets.
Linux kernel documentation says: http://tldp.org/HOWTO/Adv-Routing-HOWTO/lartc.kernel.rpf.html

Any one know how if this can be done with routeros?

Cheers!

Ros has also counters on firewall rules counting each hit. If you need big testing you need to build lab either physically or virtually. If I am right, you can run virtual ros without license for 24 hours for free.

Hi

Thanks. I know. From production point of view it’s nice to see if a certain feature drops packets.

Use the RP Filter saves me from many firewall rules.
Linux kernel seems to be able to log what is dropped by RP.

Cheers
