Hi,
Could you post more of your configs. From your output I am guessing that
R1,R2 and R4 is running a OSPF point-to-multipoint network. However from
the following I noticed some problems:
On R1 you have a OSPF host to R2:
> O 140.4.70.2/32 [110/64] via 140.4.70.2, >00:03:31, Serial0
On R2 you have a OSPF host route to R1:
> O 140.4.70.1/32 [110/64] via 140.4.70.1, >00:05:24, Serial0
No where on R1 or R2 is a OSPF route to R4 (guessing 140.4.70.4)
Also on R1 I believe you are also doing redistribution because of:
> C 150.100.1.0 is directly connected, Ethernet0
Then showing up in R2 as:
> O E2 150.100.1.0 [110/20] via 140.4.70.1, 00:05:24, Serial0
The problem lies somewhere in your OSPF config or your frame-relay config.
Configuring R4 to redistribute connected will not work because on R4:
> 130.1.0.0/24 is subnetted, 1 subnets
> i L1 130.1.6.0 [115/20] via 140.4.46.6, Serial1
The route is learned from R6, not directly connected. As a side note
you would have to redistribute connected with a route map on R4
in OSPF to get R1 and R2 to learn the 140.4.46.0 network between
R4 and R6 once you sort out the intial problem. Best of luck.
Danny
