Enquiry on Inverse Mask

RouterOS Forwarding Protocols
1

Hello all,

I am relatively new to RouterOS. I used Vyatta in the past.

We are running BGP with 2 full routes upstream ISP.

In the past, we use policy/route map/inverse-mask to match the incoming filter.

Specifically, we use the following to match - if incoming prefix is ..192-255.* , then set the local preference higher.

     rule 10 { 
         action permit 
         description "For x.x.192.x - x.x.255.x" 
         source { 
             inverse-mask 255.255.63.255 
             network 0.0.192.0 
         } 
     }

However, I cannot find the similar in the RouterOS. Do you have any idea?
Or in RouterOS, is there easy way to select around 100,000 routes in the Route/Filter ?

Thank you very much for your kind attention
Regards
George

There is generally used exclamation mark to invert the value. Check if it apply to your case.
