Lab 20: Integrating RIP Networks: Redistribution, Route Filtering, and Control-Part I

Lab 19: Configuring Classical IP Using SVCs on Cisco 7 XXX Routers, RFC 2225 ”Part II

Lab Walkthrough

You use the same IP addressing and IP routing protocol as you used in the previous lab. The steps necessary to perform these tasks are presented here for your reference. The ATM network is SVC-based. Your IP connectivity must extend through the ATM network, creating a fully meshed environment.

This lab illustrates the extension of IP connectivity using Classical IP. In addition to Classical IP implementation, you use ILMI for a dynamic ATM address prefix assignment.

Table 8-12 lists and describes the commands that are necessary to complete this lab.

Table 8-12. Lab Command Summary

Command	Description
atm pvc	Used for signaling and ILMI PVCs creation
atm arp-server self	Configures the ARP server for one LIS
atm arp-server nsap	Configures the ARP server client
atm esi-address	Configures the ATM ESI portion of the NSAP (AESA) address
debug atm events	Shows the creation of PVCs between router and switch
debug atm arp	Shows ATM ARP events
show ip route	Shows the IP routing table
ping	Tests connectivity at Layer 3

Refer to Figure 8-9 to complete the steps described in the sections that follow.

Step 1. Configure the Router Parameters

Configure your router with the following parameters:

• Host name : R n (where n is the router number)

• Enable password: atmlab

• Virtual terminal/console password: cisco

• IP routing: EIGRP

• EIGRP autonomous system number: 100

• IP as your only routed protocol

Example 8-14 shows the results of your configuration, demonstrated for R1.

Example 8-14 Configuring the Router Parameters

 R1(config)#  hostname R1   !   enable password atmlab   !   router eigrp 100   network 165.128.0.0   !   line con 0   exec-timeout 0 0   line aux 0   line vty 0 4   exec-timeout 0 0   password cisco   login   !  

Step 2. Configure the IP Addresses for the ATM 1/0.2 Interfaces

Configure the IP addresses for the ATM 1/0.2 interfaces with the IP addresses identified in Table 8-13.

Table 8-13. IP Address Assignment

Router	ATM1/0.1
R1	165.128.200.1/24
R2	165.128.200.2/24
R3	165.128.200.3/24
R4	165.128.200.4/24
R5	165.128.200.5/24

Example 8-15 shows the configuration for R1.

Example 8-15 IP Address Configuration for Router R1

 R1(config)#  interface atm1/0.2 multipoint   ip address 165.128.200.1 255.255.255.0  

Step 3: Configure Two PVCs ”Signaling and ILMI on the Major Interfaces on Every Router

Example 8-16 shows how to perform the configuration for this step on Router 1.

Example 8-16 Configuring the Signaling and ILMI on PVCs

 R1(config)#  interface atm1   atm pvc 1 0 5 qsaal   atm pvc 2 0 16 ilmi   interface atm 1/0.2 multipoint   ip address 165.128.200.1 255.255.255.0  

Step 4: Configure LS1010 to Handle PVCs

In the CCIE lab, the ATM switch is preconfigured; However, for your CCIE preparation, you are required to configure your own switch as demonstrated in Example 8-17. The configuration is as follows .

Example 8-17 Configuring an ATM Switch to Be PVC-Aware

 ATM-Switch#  version 11.3   no service pad   no service udp-small-servers   no service tcp-small-servers   !   hostname ATM-Switch   !   enable password atmlab   !   no ip domain-lookup   !   atm address 47.0091.8100.0000.0010.0739.a101.0010.0739.a101.00   atm router pnni   node 1 level 56 lowest   redistribute atm-static   !   interface ATM0/1/0   no ip address   no atm auto-configuration   atm uni version 3.1   !   interface ATM0/1/1   no ip address   no atm auto-configuration   atm uni version 3.1   !   interface ATM0/1/2   no ip address   no atm auto-configuration   atm uni version 3.1   !   interface ATM0/2/0   no ip address   no atm auto-configuration   atm uni version 3.1   !   interface ATM0/2/1   no ip address   no atm auto-configuration   atm uni version 3.1  

Step 5: Assign the ESI Portion of the NSAP Address to Router Interfaces

This step involves assigning the ESI portion of the NSAP address to the interface atm1/0.2 of all the routers, using Table 8-14.

Table 8-14. IP Address Assignment

Router	ESI Portion of the Address
R1	0001.0001.0001.00
R2	0002.0002.0002.00
R3	0003.0003.0003.00
R4	0004.0004.0004.00
R5	0005.0005.0005.00

Example 8-18 shows the configuration for this step by using R1.

Example 8-18 Mapping the ESI Portion of the NSAP Address to the atm1/0.2 Interface

 R1(config)#  interface atm1   atm pvc 1 0 5 qsaal   atm pvc 2 0 16 ilmi   interface atm 1/0.2 multipoint   ip address 165.128.200.1 255.255.255.0   atm esi-address 0001.0001.0001.00  

Step 6: Define the Address of the ATM ARP Server

This step involves defining the address of the ATM ARP server in R1, R3, R4, and R5, and defining R2 to be the ATM ARP server.

R2 is the ATM ARP server that is consulted by R1, R3, R4, and R5 to resolve between IP and ATM addresses. Example 8-19 shows how to configure R2 as the ATM ARP server.

Example 8-19 Configuring R2 as the ATM ARP Server

 R2(config)#  interface atm1   atm pvc 1 0 5 qsaal   atm pvc 2 0 16 ilmi   interface atm 1/0.2 multipoint   ip address 165.128.200.2 255.255.255.0   atm esi-address 0002.0002.0002.00   atm arp-server self  

R1, R3, R4, and R5 are the clients . The configuration of a client must have the ATM ARP server NSAP address. Example 8-20 shows the configuration of a client by using R1 as the example.

Example 8-20 Configuring the ATM ARP Server Clients

 R1(config)#  interface atm1   atm pvc 1 0 5 qsaal   atm pvc 2 0 16 ilmi   interface atm 1/0.2 multipoint   ip address 165.128.200.1 255.255.255.0   atm esi-address 0001.0001.0001.00   atm arp-server nsap 47.0091.8100.0000.0010.0739.a101.0002.0002.0002.00  

Notice that the NSAP address of R2 was created using the prefix from the LS1010 and the ESI portion that was assigned to R2.
