Re: preferring OSPF inter-area compared to intra-area

I've clear in my mind what I want to do but I don't understand how to do it

R6 reaches R3 L0 since it's intra-area (Area2)
R6 can also reach R3 L0 via R1 since there are couple of VLs, therefore
inter-area.
from R1 I can ping R3 L0

I want to filter T1, T2 about R3 in R6. I don't think this is possible, but
I could filter through a route-map filtering via prefix-list + ip
source-route. Unluckly I'm able to get this working.
If would be able to filter out this from my rib R6 should be able to see
only R1 as valid path to R3.

Is my thinking correct? Can I filter via a route-map, matching ip
prefix-list and ip route-source and should this work?

if so we can go ahead an see if my route-map is then wrong.

thanks a lot Carlos!
