# Configure the interface serial 1/0 to allocate the IP address 10.0.0.1 to the peer.
The peer may accept this assigned address, or use its self-configured address, or
have no IP address.

Description
Use the ppp lqc command to enable PPP link quality control (LQC).
Use the undo ppp lqc command to disable PPP link quality control.
By default, PPP LQC is disabled.
By default, the arguments resume-percentage and close-percentage are equal. But
in actual configuration, the resume-percentage must not be smaller than
close-percentage.

PPP LQC functions to monitor the quality of PPP links, including those in MP
bundles. A link goes down when its quality drops below the close percentage and
goes up when its quality exceeds the resume-percentage. To avoid flapping, a link
experiences a delay before it is reused.

experiences a delay before it is reused.
Before you enable PPP LQC, the PPP interface sends keepalives to the peer every
some time. After you enable LQC on the interface, it sends link quality reports
(LQRs) instead of keepalives to monitor the link.

When link quality is normal, the system calculates link quality based on each LQR
and disables the link if the results of two consecutive calculations are below the
close-percentage. Once the link is disabled, the system starts to calculate link
