You can use the following command
ppp quality percentage
another way of doing the same is to use Subinterfaces .so that even the PVC
is down I am getting
down/down and traffic is re routed thro ' otehr router.

Subject: Re: HSRP tracking of Frame ciruits
Johnny,
One problem with this is the router on the other end of the pvc might
not be aware the link from RTC into the frame cloud went down. If the
link on RTRA's side doesn't go down then hsrp wouldn't decrement RTRA's
priority and RTRB wouldn't then become primary. However, I believe there
is a new command that does ppp end-to-end link quality checks and may
allow this to work. I don't recall the command, perhaps someone else can
provide that. Given that this command will do what we want, here's how
you would do the hsrp config:
rtra:
inter e0
ip add 1.1.1.2 255.255.255.0
standby 1 ip 1.1.1.1
standby 1 priority 105 preempt
standby 1 tracking serial 0
rtrb:
int e 0
ip add 1.1.13 255.255.255.0
standby 1 ip 1.1.1..1
standby 1 priority 100 preempt
The reason I set rtra's priority to 105 is the default value for
decrementing the priority is 10. If s0 went down the priority for rtra
woudl become 95 and rtrb would become the active router. You shouldn't
need a tracking command on rtrb because if it went down there would be no
need to decrement it and have rtra become active because it's serial link
would already be down. The reason for this is if rtra serial link had
come back up the priority would have gone back to 105 and it would have
already have become the active router. Note: rtrb priority 100 wasn't
needed, it's 100 by default, just wanted everyone to see it.
