Typically the hub will only send the youngest until it sees it still has a
neighbor sending a younger one (perhaps when 10 became active as well).
If there is some other issue that you have going on (MTU? Area? Whatever?)
that prevents a full neighbor from forming and perhaps getting torn down
then that may explain why it goes away. But the spoke with the 10-key would
be the one who initiates things.
Try "debug ip ospf adjacency" and "debug ip ospf events" on both sides (that
have key 10) and see if anything else leaps out.

Scott,
Just wanted to know why my router is sending only key 20 for couple of
minute then send both key 10 ,20 and then again only 20.. still I am having
problem on hub and spoke in non brodcast network in using two keys...is
there any change in behaviour if we use p2mp network type or non brodcast
type with neighbour command

Scott, I was working on a lab from IPExpert WB8, lab36, My stumbling
block was the hub router was only using one key ... the youngest. In the
following config, R2 is the hub, with R5, R6 as spokes.
Could someone tell me where did I go wrong?
