In the verification we have them remove the DLCI from the local
subinterface to bring the subinterface down. There used to be a note in
the solutions guide about testing the backup interface command but it
may have been removed when ISDN was removed. Guess it should be added
back ;-)

Even in the dialer days, using "shutdown" never made the backup
interface
commands work. I guess the router assumes you know what you are doing
and
it doesn't need to react!
Try doing something different like on the other end, pull a cable or
something like that. You should see it work then.

Subject: Backup Interface of a Subinterface IE Lab 9 task 3.3
Hi all,
The requirement says that if line protocol of subinterface goes down the
backup interface shall come up. Now if I apply solution given in WB,
which
is
interface Serial0
no ip address
encapsulation frame-relay
no frame-relay inverse-arp
!
interface Serial0.401 point-to-point
ip address 148.1.0.4 255.255.255.0
backup delay 0 300
backup interface Serial1
shutdown
frame-relay interface-dlci 401
and shutdown int s0.401, it puts backup interface in Disabled mode. But
if I
apply same config on S0, then its OK if line protocol goes down on S0,
S1
comes up, but if you just shutdown S0.401 it does not bring S1 up, so
doesn't meet the requirement!!! Any solution???
Regards,
Mohammad Zahed Saeed
