Hello.
You can resolve the actual routes with 'ip route get' command.
Something like this: ip -d route get <dst> from <src> iif
<input-interface>. It will show the table number if table is not main.
ip route get command also supports the filrewall mark specifing (ip -d
route get <dst> fwmark <mark-value>).

It will also honor names in /etc/iproute2/rt_tables

ip also supports realms which might help with troubleshooting.
I'm not aware of anything for ip like iptables's trace.
