Hey - I've left some high level feedback:
- The sentence ending with
/etc/iproute2/rt_tables.d/*.conf.The network role does not create...` is missing a space after the period; updating this will avoid a rendering/reading glitch. - You’ve duplicated the
ansible.builtin.lineinfileexample in both therouteandrouting_rulesections; consider extracting this into a single shared note or referencing one section from the other to reduce future drift between the two examples.

I think the recommendation for the user should be to insert the conf file in
/etc/iproute2/rt_tables.d/{{ item.name }}.conf`

Same here,
/etc/iproute2/rt_tables.d/{{ item.name }}.conf`

Thanks @rajeshrah22 I have Updated the examples to use -> /etc/iproute2/rt_tables.d/{{ item.name }}.conf` in both sections.

What this PR does
Closes #536
Two documentation improvements to the
routeandrouting_rulesectionsbased on user confusion reported in the issue thread.
Change 1 — Named routing table creation example
The README already mentions that users must ensure named tables are defined
in
/etc/iproute2/rt_tablesor/etc/iproute2/rt_tables.d/*.confbeforeusing them, but gave no guidance on how to do this.
Added an
ansible.builtin.lineinfileexample showing how to create namedrouting table entries alongside the network role — as suggested by @tyll in
the issue thread.
Change 2 — initscripts provider limitation note
Added a note in the
Limitationssection clarifying thatrouting_ruleand named
tablereferences inrouteare not supported when using theinitscriptsprovider.This was explicitly requested by @alessard-trackforce who spent 4 hours
debugging this undocumented behavior.
Testing
Documentation-only change. No code was modified.
Verified the markdown renders correctly locally.
