Hello all,
I know this is elementery ospf stuff but Im drawing a blank for some reason.
Im struggling with the proper way to handle this scenario.

Router R has loopbacks 10 (10.10.10.1/24) and 20 (20.20.20.1/24)

Router R has equal links to A and B.

Routers A and B exist on a common lan with router C

Router C has loopbacks 30 (30.30.30.1/24) and 40 (40.40.40.1/24)

When net 30 wants to talk to net 10 I always want it to take the path
through A and viceversa when 10 wants to talk to 30

By the same token when 40 wants 20 or 20 wants 40 I always want to
take the path through B

no statics of course ;)

Ive tried multi areas with distribution lists and route filters etc
but im having trouble getting it to work and still have the links R-A
and R-B pass all traffic should one or the other fail.

If anyone could throw me a bone Id sure appreciate it!!!!!!

Best Regards,
