So, what are you suggesting to do?
Here is an output of the map-classes applied to the FR DLCIs: Anything
wrong with them?

Subject: Re: Weird Interface Dependencies
Salau,
If the QOS policies applied on the interface are not optimal,
it can cause the interface queues to fill up and hence no control
messages will flow through the interface to keep the interface up. In
your case if the Lmi propagation is effected between the router and the
frame switch the interface would go down.
Something to investigate.
HTH,
Tarun

Hello Experts,
As anyone come across issues where a serial connection (say
s0/1) going
down, tend to bring down another serial connection.
The scenario is that, say RouterA has 2 serial interfaces s0/1
and s0/2.
s0/1 is a ppp connection via a V100 satellite link, and s0/2 is
a
frame-relay connection with several subinterfaces ... Say
s0/2.1,s0/2.2,s0/2.3,s0/2.4,s0/2.5 etc.
The problem is, whenever s0/1 goes down, it takes s0/2 main
interface
down with it, which in turn take down all the sub-interfaces
with it.
Is there any reason why this should be, I'm guessing hardware
related
fault on the Hub Router, or a software bug ... Anyone come
across this,
please let me know.
