route is an old tool. A more advanced alternative, the iproute2 package was introduced two decades ago.
(I never bothered to learn to read the output of 'route'.)

The iproute2 shows routes with:

Code: Select all

ip ro

(which is actually a shorthand for ip route show)
One would add a route with:

Code: Select all

ip ro add 10.6.51.64/29 via 10.156.254.33

However, if you do have NetworkManager.service in use (which is the default), the you would not set route with 'ip' (or 'route'), except temporarily. You would would configure your connections with NM.
For example (assuming the name of connection is 'bond1'):

Code: Select all

nmcli connection modify bond1 +ipv4.routes "10.6.51.64/29 10.156.254.33"
