Hello,
I have very similar problem with Intra preffered path and asymmetric
routing during the link beardown.
I configured OSPF on R1,R2,R3 ( R4,R5 only BGP ):
Network A
|
R3 ( as stub no-summary )
/ \
/ \
R1 ----- R2
| |
| |
R4 ---- R5
\ /
Network B
Primary links are: R1-R4 and R1-R3
Backup : R3 - R2 & R2-R5
OSPF :
R1 to R2 Area 0
R1 & R2 to R3 Area 1 as stub no summary
Everything is ok until link R1-R4 went down.
Traffic from Network B to Network A is going through: R5- R2- R3
Traffic from Network A to Network B : R3 - R1 - R2 - R5
Ping and traceroute works perfect but transmision not.
I thought that cisco support asymmetric routing but it doesn't work.
Has someone got the idea how change OSPF configuration or how
allow pass asymmetric traffic in this scenario ?
For R3 is enough to get default route.
Thanks in advance.
Regards,
Michal

umm... what do you mean? redistribute connected makes the route External, not Inter-Area. The way you asked the question in the beginning definitely indicates that you have to use Virtual Link
