PPP Concepts

For example, in Figure 2-5, the acceptable outbound and inbound link quality

conﬁgured on router A for the PPP interface is 100 percent. After ﬁve LQR

periods, router A calculates the outbound and inbound link quality averages and

determines that the inbound link quality average is below the 100 percent

threshold (in this case, 90 percent). As a result, router A disables the link.

Outbound average after 5 LQR periods = 100%

Inbound average after 5 LQR periods = 90%
