The solution doesn't involve shutting down the subinterface. Check over
the solution and in particular look over the verification as it shows
you how to test this out.

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
