Router#configure terminal
Router(config)#interface serial 0/0
Router(config-if)#encapsulation ppp

Point-to-point software compression can be configured on serial interfaces that use PPP encapsulation. Compression is performed in software and might significantly affect system performance. Compression is not recommended if most of the traffic consists of compressed files.

To configure compression over PPP, enter the following commands:

Router(config)#interface serial 0/0
Router(config-if)#encapsulation ppp
Router(config-if)#compress [predictor | stac]

Enter the following to monitor the data dropped on the link, and avoid frame looping:

Router(config)#interface serial 0/0
Router(config-if)#encapsulation ppp
Router(config-if)#ppp quality percentage

The following commands perform load balancing across multiple links:

Router(config)#interface serial 0/0
Router(config-if)#encapsulation ppp
Router(config-if)#ppp multilink
