CCNA LAB 97: Configuring Multilink PPP (MLPPP)

小乔

Lab Objective
The objective of this lab exercise is for you to learn how to configure a Multilink PPP connection.


Lab Purpose:
MLPPP is a feature that will allow you to provide redundancy and some sort of load balancing by using two links (interfaces) and the benefits of the encapsulation protocol of PPP. As a Cisco engineer, as well as in the Cisco CCNA exam, you will be expected to know how to implement MLPPP functionality.

Certification Level:
This lab is suitable for ICND2 and CCNA certification exam preparation.

Lab Difficulty:
This lab has a difficulty rating of 7/10.

Readiness Assessment:
When you are ready for your certification exam, you should complete this lab in no more than 10 minutes.


Lab Topology:
Please use the following topology to complete this lab exercise:




Task 1:
Configure hostnames on R1 and R2 as illustrated in the topology.

Task 2:
Create a Multilink interface on R1 and R2 with the following settings:

Multilink group: 1
Encapsulation type: PPP
IP address: As in the diagram
Task 3:
Configure both Serial interfaces on R1 and R2 to join Multilink group 1.


Task 4:
Make sure that there is reachability between R1 and R2 via the MLPPP interface and that the interface is up and running.

Configuration and Verification
Task 1:
For reference information on configuring hostnames, please refer to earlier labs.

Task 2:
R1#conf t
Enter configuration commands, one per line.  End with CTRL/Z.
R1(config)#int multilink 1
R1(config-if)#encapsulation ppp
R1(config-if)#ppp multilink group 1
R1(config-if)#no shutdown
R1(config-if)#ip add 192.168.10.1 255.255.255.252
R1(config-if)#end

R2(config)#int multilink 1
R2(config-if)#encapsulation ppp
R2(config-if)#ppp multilink group 1
R2(config-if)#no shutdown
R2(config-if)#ip add 192.168.10.2 255.255.255.252
R2(config-if)#end
Task 3:
R1#config t
Enter configuration commands, one per line.  End with CTRL/Z.
R1(config)#int serial0/0
R1(config-if)#encapsulation ppp
R1(config-if)#ppp multilink group 1
R1(config-if)#no shutdown
R1(config-if)#exit

R1(config)#int serial0/1
R1(config-if)#encapsulation ppp
R1(config-if)#ppp multilink group 1
R1(config-if)#no shutdown
R1(config-if)#exit

R2(config)#int serial0/0
R2(config-if)#encapsulation ppp
R2(config-if)#ppp multilink group 1
R2(config-if)#no shutdown
R2(config-if)#exit

R2(config)#int serial0/1
R2(config-if)#encapsulation ppp
R2(config-if)#ppp multilink group 1
R2(config-if)#no shutdown
R2(config-if)#exit
Task 4:
R1#sh ip int brief
Interface   IP-Address    OK?   Method    Status     Protocol
Serial0/0   unassigned    YES   unset     up         up      
Serial0/1   unassigned    YES   unset     up         up      
Multilink1  192.168.10.1  YES   manual    up         up

R2#sh ip int brief
Interface   IP-Address    OK?   Method    Status     Protocol
Serial0/0   unassigned    YES   unset     up         up      
Serial0/1   unassigned    YES   unset     up         up      
Multilink1  192.168.10.2  YES   manual    up         up

R1#ping 192.168.10.2

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 192.168.10.2, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 56/67/96 ms
