Hi,
What is the equivalent in RouterOS of the command "show ip route x.x.x.x/24 longer-prefixes" (used on most systems like Cisco/Juniper/Quagga/...)
Thank you,
Mickael

This is the equivalent of longer prefixes:
This is for an exact prefix length:

I tried this command:
[MikroTik] /ip route> print where dst-address in 8.8.8.0/20

On a CCR1009, it looks like even after 10 minutes, nothing appears.
It should show all the routes matching inside the /20.

Any idea why?

Doing ip route lookup with full tables or multiple tables can take a very long time....
Exact matches are much faster..
or doing route look up of smaller prefix with a listing of all routes with larger prefix within it are faster via winbox.

But in general anything other than exact route look up can be very slow...
