Hell all, In this section R2 is redistributing OSPF into BGP and is advertising it to R6. At the same time, R2 and R6 are ospf neighbors and are advertising ospf routes to each other. Now there is a question in this section that reads as follows.
"R6 should not receive any routes from R2 that are from the ospf domain. No network statements are allowed.". After reading this question, I used "ip ospf database" filter command and filtered all the LSA's that were send to R6 from R2 as I was not allowed to use network statement that would allow me to disable OSPF on the interface. However, P.G uses a solution where it filtered OSPF routes that were redistributed into BGP. I think this question wants us to not have the ospf routes propagated to the OSPF neighbors via BGP routes. I think this question needs one simple modification. Instead of saying "any ospf routes" that includes OSPF routes only (as per the English language understanding), Instead it should say BGP routes. That means it should read something like this. "R6 should not receive any BGP routes from R2 that are from the ospf domain. No network statements are allowed" I know there will always be a language issue with CCIE. But I think making something difficult by using a language twist makes it more confusing than technically challenging. Thanks Suresh
