Both RouterA nd RouterB are connected back to back through Serial Interface0.Encapsulation is HDLC on both sides. Clock Rate is enabled on RouterB(DCE). RouterA Serial Interface IP address is 20.1.1.1/8. RouterB Serial Interface IP address is 20.1.1.2/8. 'Show INterface Serial 0' command shows that both interfaces are up and protocol is up.

Serial Interface Definition

Use the show interface command on any of the serial interfaces to view the current encapsulation. The default serial encapsulation on Cisco routers is HDLC. Loopback not set If you check all the active serial interfaces. Change the encapsulation type on the link between R1 and R2. The encapsulation will be set to. PPP Protocol and Encapsulation method Explained. This tutorial explains basic concepts of PPP, PPP encapsulation, PPP authentication PAP, PPP authentication CHAP and how to configure PPP protocol on Cisco router step by step. At this time both routers are running default encapsulation in serial interface. HDLC is the default encapsulation. By default, Cisco devices use the Cisco HDLC serial encapsulation method on synchronous serial lines. However, if the serial interface is configured with another encapsulation protocol and you want to change the encapsulation back to HDLC, enter the interface configuration mode of the interface that you want to change. Understanding Data Link Layer Encapsulation will answer important question: Why layer 2 uses different set of protocols for different type of cables to. Compared the destination IP address to its routing table and decided to route the IP packet through its serial interface to Branch-Office router (2). Encapsulated the IP packet into a NEW.
