Last input never, output never, output hang neverįinally, configure PPP encapsulation and IP address on Router-A serial 0/0/0 interface. Reliability 255/255, txload 1/255, rxload 1/255Įncapsulation PPP, loopback not set, keepalive set (10 sec) Serial0/0/0 is up, line protocol is up (connected) The show interfaces serial 0/0/0 confirms that PPP encapsulation is enabled on the interface : Encapsulation PPP, loopback not set, keepalive set (10 sec) Router-B#show interfaces serial 0/0/0 Don't forget to enable the interface with a no shutdown command. Router-B beeing the DCE side of the serial link, the 192.168.10.5/30 IP address is configured on Router-B serial 0/0/0 interface.
PPP authenication can be oprtionnally configured using the following IOS commands which are not used in this lab : The encapsulation ppp configures PPP protocol on the serial interface. Then, configure PPP encapsulation and IP address on Router-B serial 0/0/0 interface. Router-B beeing the DCE, clock rate has to be configured on Router-B serial 0/0/0 interface Router-B(config)#interface serial 0/0/0 Configure the routers with the following parameters In this example, Router-A is the DTE side, and Router-B the DCE side (DCE V.35, clock rate set). The show controllers command is used to determine which side of the cable is the DCE side. Use the connected laptops to find the DCE and DTE routers Check IP connectivity between the two routers using the ping command.ġ. Configure the routers with the following parameters :ģ. You can connect to the routers using CLI.Ģ. Use the connected laptops to find the DCE and DTE routers.
Practicing this labs will help you to better understand what is a DCE, a DTE, and aclock rates on a serial router interconnection and make you ready for the CCNA ppp labs and simlets.ġ. This lab will test your ability to configure PPP on a serial link in Packet Tracer 8.0. The clock rate command in the interface configuration mode enables the router at the DCE end of the cable to provide the clock signal for the serial link. This clock is received by the DTE device. With a back-to-back serial connection, the ISR router connected to the DCE end of the serial cable provides the clock signal for the serial link. However, to change the encapsulation back to HDLC from PPP, use the following command from interface configuration mode: Router(config-if)#encapsulation hdlc HDLC is the default encapsulation on serial links in a Cisco router. PPP has to be used when communicating with non-Cisco devices. This field makes it possible for a single serial link to accommodate multiple network-layer protocols.Ĭisco’s HDLC is a point-to-point protocol that can only be used on serial links or leased lines between two Cisco devices. Because the standardized HDLC cannot support multiple protocols on a single link (lack of a mechanism to indicate which protocol is carried), Cisco developped a proprietary version of HDLC, called cHDLC, with a proprietary field acting as a protocol field. HDLC is a data link protocol used on synchronous serial data links.
