You must use a multipoint interface on r2 or use "ip ospf netwwork
point-to-multipoint" on both interfaces. BUT the lab states that you cannot
use any "ip ospf network .." statement, so you have to use a multipoint
interface. This will make the interface timers the same. If you do "sh ip
ospf int s0" on r2 and "sh ip ospf int s0.2" on r1, you see that they have
different timer values. For adjacency you need the same timer values.

Hi All,
I am having problems with this lab trying to get R2 and R3 to OSPF peer over
hub and spoke Frame Relay . R1 is the hub and both R2 and R3 the spokes. I
include the relevant config excerpts. Both R2 and R3 can ping each other -
R1
is in a full state with both R2 and R3 so where am I going wrong?
Many thanks for your help.
