Subject: RE: General Redistribution Question
Here is how I do it, perhaps people that got 80 points will have a
better answer.
I would get basic full redistribution working, verify there are NO LOOPS
(the ping script failing may be an indicator of this). Then I would
recommend going back drawing out redistribution, and if there is
particular path a network should take from point A to point B, consider
how best to do it, taking into account any restrictions. Don't be
overwhelmed by redistribution, it's not bad at all.
The biggest mistakes I think are...
-forgetting some routers are doing redistribution from CONNECTED to a
protocol not a protocol to a protocol (don't forget the redistribution
command takes from the FIB, not the RIB).
-forgetting to take into account OSPF/RIP have no built in way to detect
external routes, and need "distance" commands to force protocol
preference.
-spending time on non-essential tasks under an IGP which may only be
worth 3 points. Spend the time on the EASY ip services, security,
multicast, etc.
points you do know. Once those are verified go back and add the nice to
haves. Be honest about adding points to your perceived score. 80 is a
big number when you're counting by 2 and 3.
Know how to make a "ping macro" on router's also, if you are going to
run a ping script. Know it just as fast and as cold as } { [ puts "exec
ping $i repeat 2"] }
LOL

Agreed,
But for the lab, I was thinking there might be a general best approach
to redistribution in 3 point scenarios with redundancy.

This advice appears Wendell Odom's CCIE exam certification guide.
There is a whole chapter on detailed redistribution. I am fairly
confident if Wendell Odom sat the lab today, he would pass.

Subject: General Redistribution Question
I'm working through IEWB RS Vol2 LAB 2 and had a general question about
what's the best approach for two way redistribution.
To tag or not to tag? I'm thinking distance is best if there's two
two-way redistribution points and you need redundancy. If you have three
two-way redistribution points, maybe going with tagging or a combination
of tagging and distance is best. Or maybe not. I guess I'm looking for a
hard rule of thumb for certain situations.
Thanks,
Ryan
