Hi,
Below is queston 16 from ECP1's final exam which I
could not come up with any answer:
"Configure dial backup so that R2 calls R1 when routes
learned over the Frame-Relay interface disappear. Do
not use the backup interface command. Make sure the
ISDN link does not stay up indefinitely. (Include the
backup link in OSPF area 33)."
The general requirement for this exam is no static
route unless noted otherwise, which means I cannot use
the floating static. That makes me to think the only
option I have is to use dialer watch, but that will
make the ISDN staying up until Frame-Relay network
comes back up. Don't bother ip ospf demand-circuit
with dialer watch, as when dialer idle-timeout
expires, it will check the routing table and keep the
line up.
Other than backup, floating static and dialer watch,
is there other way to solve this problem?
By the way, please include me in the copy list when
you send your reply, as I'm having troubles to receive
groupstudy emails recently.
Thanks,
Chang
