Hi group,
In working through lab 23 in Solie's Practical Studies I ran into the
following. The requirements for the lab call for filtering the 172.16.3.0
network on the "barneys" router. Another requirement is for "solar_bucks" to
inject a default route to the internet router. Lastly, "g_and_s" should
prefer a path though barneys for all internet traffic.
I configured a static route to 0.0.0.0 0.0.0.0 on solar_bucks and
redistributed static to create the default route. On barneys I filtered the
172.16.3.0 route out s0.1 and s0.2. On g_and _s and solar_bucks I increased
the delay to make barneys the preferred route. So far everything looks good.
Here's my problem. 173.16.3.0 is NOT in the g_and_s route table but I can
ping it. (route table follows). In a way this makes perfect sense to me
since I have a default route that now goes through that router. However, does
this mean that I am not meeting the requirements of the lab?
Thanks for the sanity check!
