Lab 18: Configuring PVCs on Cisco 7 XXX Routers, RFC 2684 ”Part II

Lab Walkthrough

You need to configure the IP routing protocol and IP addressing, which are used in both labs. After the initial configuration is complete, you need to set up eight PVCs to the other routers, creating a fully meshed topology. Your IP connectivity must extend through the ATM network.

Table 8-9 lists the commands that you need to complete this lab.

Table 8-9. Lab Command Summary
Command Description
router eigrp Turns on the EIGRP routing protocol on the router
atm pvc Sets up bidirectional permanent virtual circuits
map-list Maps a Layer 3 network address to a PVC
show atm vc Displays the configured virtual circuits on the router
show atm interface atm Displays more detail about the specified interface
show atm map Displays the map-lists that were created by the user
Debug atm events Displays the creation of PVCs between the router and the ATM switch
show ip route Displays the IP routing table
ping Tests connectivity at Layer 3

Refer to Figure 8-8 to complete the following exercises for this lab.

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 8-9 shows the configuration for R1.

Example 8-9 Router R1 Configuration 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 Ethernet 0 and ATM 1/0.1 Interfaces

Configure the IP addresses for the Ethernet 0 and ATM 1/0.1 interfaces with the IP addresses, as identified in Table 8-10.

Table 8-10. IP Address Assignment
Router E0 ATM1/0.1
R1 165.128.1.1/24 165.128.100.1/24
R2 165.128.2.2/24 165.128.100.2/24
R3 165.128.3.3/24 165.128.100.3/24
R4 165.128.4.4/24 165.128.100.4/24
R5 165.128.5.5/24 165.128.100.5/24

Example 8-10 shows the configuration for R1.

Example 8-10 IP Address Configuration for Router R1
 R1(config)#  interface e0   ip address 165.128.1.1 255.255.255.0   interface atm1/0.1 multipoint   ip address 165.128.100.1 255.255.255.0  
Step 3: Configure a PVC to Every Other Router

To create a fully meshed ATM PVC network, you need to configure a PVC to every other router. Use AAL5SNAP. Use Table 8-11 for the VPI/VCI number assignment.

Table 8-11. VPI/VCI Assignment
From To VCD VPI VCI
R1 R2   112
  R3   113
  R4   114
  R5   115
R2 R1   121
  R3   123
  R4   124
  R5   125
R3 R1   131

  R3   143
  R5   145
R5 R1   151
  R2   152
  R3   153
  R4   154

Example 8-11 shows the configuration for R1.

Example 8-11 PVC Configuration for Router R1
 R1(config)#  interface atm1/0.1 multipoint   ip address 165.128.100.1 255.255.255.0   atm pvc 112 0 112 aal5snap   atm pvc 113 0 113 aal5snap   atm pvc 114 0 114 aal5snap   atm pvc 115 0 115 aal5snap  
Step 4: Configure LS1010 to Handle PVCs

In the CCIE lab, the ATM switch is preconfigured. For your CCIE preparation, however, you are required to configure your own switch, as demonstrated in Example 8-12. The configuration is as follows .

Example 8-12 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   atm maxvpi-bits 3   atm maxvci-bits 10   atm pvc 0 112  interface  ATM0/1/1 0 121   atm pvc 0 113  interface  ATM0/1/2 0 131   atm pvc 0 114 interface  ATM0/2/0 0 141   atm pvc 0 115 interface  ATM0/2/1 0 151   !   interface ATM0/1/1   no ip address   no atm auto-configuration   atm uni version 3.1   atm maxvpi-bits 3   atm maxvci-bits 10   atm pvc 0 121  interface  ATM0/1/0 0 112   atm pvc 0 123  interface  ATM0/1/2 0 132   atm pvc 0 124  interface  ATM0/2/0 0 142   atm pvc 0 125  interface  ATM0/2/1 0 152   !   interface ATM0/1/2   no ip address   no atm auto-configuration   atm uni version 3.1   atm maxvpi-bits 3   atm maxvci-bits 10   atm pvc 0 131  interface  ATM0/1/0 0 113   atm pvc 0 132  interface  ATM0/1/1 0 123   atm pvc 0 134  interface  ATM0/2/0 0 143   atm pvc 0 135  interface  ATM0/2/1 0 153   !   interface ATM0/2/0   no ip address   no atm auto-configuration   atm uni version 3.1   atm maxvpi-bits 3   atm maxvci-bits 10   atm pvc 0 141  interface  ATM0/1/0 0 114   atm pvc 0 142  interface  ATM0/1/1 0 124   atm pvc 0 143  interface  ATM0/1/2 0 134   atm pvc 0 145  interface  ATM0/2/1 0 154   !   interface ATM0/2/1   no ip address   no atm auto-configuration   atm uni version 3.1   atm maxvpi-bits 3   atm maxvci-bits 10   atm pvc 0 151  interface  ATM0/1/0 0 115   atm pvc 0 152  interface  ATM0/1/1 0 125   atm pvc 0 153  interface  ATM0/1/2 0 135   atm pvc 0 154  interface  ATM0/2/0 0 145   !   interface Ethernet2/0/0   ip address 10.0.0.12 255.0.0.0   !   ip classless   !   line con 0   exec-timeout 0 0   password cisco   login   line aux 0   line vty 0 4   exec-timeout 0 0   password cisco   login   !   end  
Step 5: Map Your Neighbor's IP Network Number to the Appropriate PVC

Example 8-13 uses R1 to demonstrate this step of the lab.

Example 8-13 Mapping IP Network Numbers to the Proper PVC
 R1(config)#  interface atm1/0.1 multipoint   ip address 165.128.100.1 255.255.255.0   atm pvc 112 0 112 aal5snap   atm pvc 113 0 113 aal5snap   atm pvc 114 0 114 aal5snap   atm pvc 115 0 115 aal5snap   map-group ip-Pvc   !   map-list ip-Pvc   ip 165.128.100.2 atm-vc 112 broadcast   ip 165.128.100.3 atm-vc 113 broadcast   ip 165.128.100.4 atm-vc 114 broadcast  ip 165.128.100.5 atm-vc 115 broadcast
