FREEK is used on PVCs. The PVC goes down but LMI,
frame keepalives, etc are occurring on the
physical/major interface which aren't tied to PVCs so
that traffic is keeping serial up/up. If you move the
PVCs with the FREEK option to a subinterface then kill
the PVC then the subinterface will go down because
LMI, etc isn't on the subinterface keeping it up.
Maybe think of it like this... If FREEK forced the
physical interface down then you lose LMI and how
would the router know when the PVC came back??
Like the other poster said, the only way the
physical/major serial will go up/down is if you
configure it for a different encaps type, the line
signal goes away, etc.
HTH, Erick.
