Trang 2Exercise 1) Remote frame relay switching
Objective: The objective of this exercise is configure Sydney and Melbourne (refer diagram 1) for remote frame relay switching As such they will tunnel frame relay traffic between the 2 serial0 interfaces by encapsulating this traffic
in IP and sending it across an IP backbone
a) Cable your routers as shown on diagram 1 Gibe all 4 routers appropriate hostnames and passwords Also add clocking on serial interfaces Do NOT clock faster then 38.4kbps if you have V.24 cables
b) Use network 131.108.0.0 and a /20 mask to create 3 subnets
c) Configure Sydney and Melbourne Ethernet0 for IP routing using of the allocated subnets
d) Create one loopback interface on each of Melbourne and Sydney, and assign each an IP address from the remaining 2 subnets
e) On Sydney and Melbourne configure RIP to advertise network 131.108.0.0 f) Create a tunnel connecting Melbourne and Sydney across the Ethernet IP backbone, Use the loopback interfaces as end points
g) Configure Melbourne and Sydney as frame relay (FR) switches on serial 0 Create 2 PVC’s at each end Assign them DLCI numbers 50 and 51
h) Connect Brisbane/Canberra to Melbourne/Sydney via their serial 0 Create 2 PVC’s between Brisbane and Canberra Use a NBMA approach, ie No subinterfaces
i) Use Cisco LMI signaling between Brisbane and Melbourne Use ANSI signaling between Sydney and Canberra
j) Configure Brisbane/Canberra to poll the switches every 5 seconds
k) Use show frame-relay pvc to verify that both DLCI’s are active between Brisbane and Canberra
Trang 3Exercise 2) IP across frame relay
Objective: The objective of this exercise is configure Brisbane and Canberra for
IP connectivity across the frame relay service established in the previous exercise This will be an OSPF network
a) Create one loopback interface on each of Brisbane and Canberra Configure
IP routing on both the loopback interface and frame relay interface Use 192.1.1.0 with a /26 mask to allocate the appropriate IP addressing
b) Use a frame relay map statement to map between next hot IP address and DLCI on Brisbane and Canberra Map DLCI 50 only It is necessary to turn off inverse ARP for all protocols, to avoid DLCI’s going up and down
c) Configure Brisbane and Canberra for OSPF Make the FR cloud the
backbone area Put the loopback interface on Brisbane in area 1 and the loopback interface on Canberra in area 2
d) Force the backup designated router to become the designated router on the
FR cloud Use show IP OSPF int s0 verifies your result
e) Verify that Brisbane can IP ping the loopback interface on Canberra Can Brisbane ping the Ethernet interface on Sydney? Is this the result you
expected?
