I hope this is simple, but I can't find anything that
works.
I'm unsing a six router pod. R5 is the frame
head-end, R2 and R3 are multipoint to that headend.
The frame is area 0. R6 is connected to R2 via
serial. R4 is connected to R5 via separate P-t-P
link. R4 and R6 share a common ethernet. Here's the
issue:
R6 is learning about the local routes on R4 via RIP
across the ethnet and redistributing them into OSPF,
area 10 which is the serial link to R2. I've set the
default metrics such that R2 should prefer R6 for
routes to R4, but no matter what I set R5 is
preferred.
Is this an area 0 preferrence? or is there something
I'm missing.
Here's R6 config:
Current configuration:

Note that R6 is using R2 as a virtual-link to area 0.
I've done some LSA/SPF/Tree debugs on both R2 and R6
after a 'clear ip rout *', and noted that R6 doesn't
ever send R2 an LSA for the 153.67.4x.x routes (all
the routes on R4 are 153.67.4x.x). I'd send that but
its lengthy.
