Ill have to check this out.  Thanks Joe.

So I guess technically a distribute-list prevents routs from getting into the 
rib not from the router receiving them?

Ed,

Guys be extremely careful with the distribute-list command in OSPF.  Check out 
this FAQ from Cisco for more information.  Remember, it is link-state so the 
LSDB must be the same across the area!

I would say as long and you look in your route table and you only see odd routs 
then your ok.  As long as they are not requiring you to use a  "prefix-list" 
you can do anything that works.



I always try to do the easy way unless I am forced not to.  Standard ACL's 
matched with distribute-list are what I use unless I have a reason not to.

Dear Experts,

I have some questions regading the VOL3 labs. So I'll start with lab7.

In lab 7 , task 3.5 , the task is asking for R9 to receive only even routes  
from BB2 via serial 0/2/0 only and the odd routes via serial 0/2/1 only. The 
solutions in the proctor guide has been configured in R6 with two long 
prefix-lists. I did the configuration in R9 with the (distribute-list in) with 
the access-lists and it gave me the same result.



Is my solution correct ?



Thanks for the reply in advance.



Khaled Al-Saholy
