Works in my test

set protocols static table 200 route 192.0.2.35/32 dhcp-interface 'eth4'

Show ip route

vyos@vyos2:~$ vtysh -c "show ip route table 200"

Did you execute renew dhcp interface ethX after adding route?

It might be a boot/slow DHCP lease issue.

The protocols_static.py conf script checks at runtime for a dhcp router. At boot, the lease might not exist yet and no route is created.

I think we need to add a dhcp client hook to call protocols_static.py to refresh any dhcp based routes.
