Configuring Point-to-Point Encapsulations

Addressing Table

Objectives

• Review routing configurations 
• Configure PPP as the Encapsulation method
• Configure HDLC as the Encapsulation method

Task 1: Review Routing Configurations.
Step 1. View running configurations on all routers.

Catatan konfigurasi routing, baik statis dan dinamis. Anda akan mengkonfigurasi kedua jenis routing dalam Tracer Paket Keterampilan Integrasi Challenge Kegiatan di akhir bab.


Step 2. Test connectivity between PCs and the Web Server.

• Open a command line from PC1.
• Issue the command ping 209.165.200.2
• Repeat with PC3.

Both ping commands should be successful. Remember to give enough time for STP and OSPF to converge.

Task 2: Configure PPP as the Encapsulation Method.
Step 1. Configure R1 to use PPP encapsulation with R2.

• R1(config)#interface serial0/0/0
• R1(config-if)#encapsulation ppp

Step 2. Configure R2 to use PPP encapsulation with R1 and R3.
Step 3. Configure R3 to use PPP encapsulation with R2.
Step 4. Test connectivity between the PCs and the Web Server.

Why does OSPF need to converge after the encapsulation change?

Task 3: Configure HDLC as the Encapsulation Method.
Step 1. Configure ISP to use HDLC encapsulation with R2.

ISP(config)#interface serial0/0/0
ISP(config-if)#encapsulation hdlc
ISP(config-if)#no shutdown

Step 2. Configure R2 to use HDLC encapsulation with ISP.

R2(config)#interface serial0/1/0
R2(config-if)#encapsulation hdlc
R2(config-if)#no shutdown

Catatan: Meskipun Hasil Periksa mungkin menunjukkan 100%, yang Konektivitas Tes akan gagal kecuali jika Anda mengkonfigurasi tidak ada perintah shutdown pada R2 dan ISP.

Step 3. Test connectivity between the PCs and the Web Server.

Use a Packet Tracer Simple PDU to check connectivity. It should be successful.
