In LAPB, since there is no master/slave relationship, the sender uses the Poll bit to insist on an immediate response. In the response frame this same bit becomes the receivers Final bit. The receiver always turns on the Final bit in its response to a command from the sender with the Poll bit set. The P/F bit is generally used when either end becomes unsure about proper frame sequencing because of a possible missing acknowledgement, and it is necessary to re-establish a point of reference. However eap does not work, just a little time Belo the config interface Multilink78 ip address 193.44.78.8 255.255.255.128 ppp reliable-link ppp ncp passive ppp multilink ppp multilink group 78 end R8#sh runn int s0/0/0 Building configuration...

This information is "encapsulated" onto the data. At Layer 3 of the model, we need IP address information. This is "encapsulated" on the data. So you see, the process of adding additional fields worth of information to the data is termed encapsulation. By the way, when a receiving machine strips this information of, that is called, de-encapsulation. -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Ahmed Haji Munye Sent: Thursday, August 18, 2011 12:06 AM To: CC IE Subject: [OSL | CCIE_RS] encapsulation data ?
