[solved]"ip address add" without adding the default (metric=0) route ?

When I use the ip address command; eg:

ip address add local 192.168.77.10/29 dev eno1

a default route with metric=0 (for the directly connected interface) is automatically added to the route table and shown with ip route show.

I've been reading the man page for ip address and I cannot figure out how to prevent it to manually created it afterwards.

Use case ?

I want to place a specific route for a specific computer before it (overriding the default route):

eg: metric=1 192.168.77.12 via 192.168.78.11 ### specific computer going via elsewhere
eg: metric=2 192.168.77.10/29 via 192.168.77.9 ### instead of default metric=0

Sure?

ip address add local 192.168.77.10/29 dev eno1 metric 2

Edit: I read your post again and might misunderstood it. If you want to route a specific IP via a specific gateway, just add the route. The metric should not be important if you have a correct network layout.

Sure.

Edit: I read your post again and might misunderstood it. If you want to route a specific IP via a specific gateway, just add the route. The metric should not be important if you have a correct network layout.

from the man page: metric NUMBER ... priority of prefix route associated with address.

I didn't figure out that a metric following ip address add ... was for the default route created by it; somehow I thought of it as a way to bind it with another already-added custom route. My fault.

I suppose this will do the trick. Thanks for your advice !
