dialer map 133.14.3.0 name r3 broadcast 8358664

hinks that 133.14.3.3 is directly connected and never installs the ospf route i
n its routing table. The isdn circuit stays up and is never brought down until
i manually clear it. But i thought the idle-timeout is supposed to check whethe
r the primary link is active and bring down the isdn circuit.
