Chuck,
I would think like a proctor. Sometimes pinging from one end to the other
will do the trick, other times you may indeed need to ping each router. For
example, you may indeed be able to test if route redistribution is working
correctly by pinging from one router in the netwrok to a router on the far
side of the network, but if you are testing whether frame-relay is set up
correctly with split-horizon, etc., you will need to ping each spoke from
each spoke. I also find it very helpful to view show ip route connected,
then show ip route, and compare the route tables for the routers side by
side. Ideally, you can bring up one window for each router and compare the
tables. It just depends, but in general, think like the proctor. What do you
have to do to verify that something is working correctly? Ask yourself this
question and then check your work.
Regards,
David Wolsefer, CCIE #5858

As most of you know, one condition for success that all of the practice labs
state is the ability to reach all parts of the network from all other parts.
I.e. ping from any interface to any interface
In terms of a general practice, I use two techniques.
1) are all the routes in my tables that I expect to be in my tables. This is
actually done incrementally as part of my configuration routine
2) I check my map for what look like the two points furthest apart and test
from there. If that is good, I make the ASSumption that things are as they
should be.
Not that I want to be saying this someplace where Lab proctors might see and
make notes about me, but I find that testing from everywhere to everywhere
might cost more time than I can afford.
Any thoughts? Techniques? Shortcuts? ( recognizing that what you say may be
used against you :-> )
Chuck
