Compression over a PPP link. (Question #59)

Consider two routers connected back-to-back over their serial links with the following configuration

Router1

interface Serial2
ip address 10.0.0.1 255.255.255.0
encapsulation ppp
no keepalive
compress predictor


Router2

interface Serial2
ip address 10.0.0.2 255.255.255.0
encapsulation ppp
no keepalive
compress stac


Note that the compression algorithms configured on each end do not match. If a ping is attempted from one router to the other, will the pings succeed? Would your answer change if the encapsulation on both serial interfaces was changed to HDLC instead?
