Re: [LARTC] one dude about rt_tables

You are correct.  It simply maps names to numbers so that you can use
something like this if you want:

# ip route add default via 10.0.0.1 table dsl-link
# ip route add default via 10.0.0.2 table t1-link

Where the rt_tables file contains:

1       dsl-link
2       t1-link

If you do not have the file /etc/iproute2/rt_tables, you can use the 
following syntax .

# ip route add default via 10.0.0.1 table 1
# ip route add default via 10.0.0.2 table 2

 : I found a solution here:

I've not seen this before and will have to read this article.  Thanks for
the link.

I do have some general documentation on the use of "ip route" and "ip 
rule" in the appendices of my documentation available here:

Let me know if you find any flaws, areas for improvement, or missing 
content.
