Ccna routing and Switching Complete Study Guide

S0/0: 172.16.10.1/30 

S0/1: 172.16.10.9/30 

S0/0: 172.16.10.2/30

S0/0: 172.16.10.10/30

MLP: 10.1.1.0/24

But first, I want you to study the configuration of the two serial interfaces on the Corp 

router that we’re going to use for making our bundle:

Corp# 

show interfaces Serial0/0

Serial0/0 is up, line protocol is up

  Hardware is M4T

  Internet address is 172.16.10.1/30

  MTU 1500 bytes, BW 1544 Kbit/sec, DLY 20000 usec,

     reliability 255/255, txload 1/255, rxload 1/255

  Encapsulation PPP, LCP Open

---

Point-to-Point Protocol (PPP) 

909

  Open: IPCP, CDPCP, crc 16, loopback not set

 

Corp# 

show interfaces Serial1/1

Serial1/1 is up, line protocol is up

  Hardware is M4T

  Internet address is 172.16.10.9/30

  MTU 1500 bytes, BW 1544 Kbit/sec, DLY 20000 usec,

     reliability 255/255, txload 1/255, rxload 1/255

  Encapsulation PPP, LCP Open

  Open: IPCP, CDPCP, crc 16, loopback not set

Did you notice that each serial connection is on a different subnet (they have to be) and 

that the encapsulation is PPP?

When you configure MLP, you must first remove your IP addresses off your physical 

interface. Then, you configure a multilink bundle by creating a multilink interface on both 

sides of the link. After that, you assign an IP address to this multilink interface, which effec-

tively restricts a physical link so that it can only join the designated multilink group interface.

So first I’m going to remove the IP addresses from the physical interfaces that I’m going 

to include in my PPP bundle.
