summary address command
Allows you to summarise OSPF to /24. The docco CD says this is for
summarising info coming INTO OSPF but it works both ways.
BUT, once you summarise OSPF to /24 the sumary is a more direct route than
the real IP range (so, routing issues). Therefore run "ip ospf network
point-to-multipoint" on the interface with the /22 mask to generate a /32
route that will give you a more specific route than the summary to make your
routing work again.
I have found that with enough patience and persistance it is possible to get
almost any route into a classfull protocol.
