Exercise 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.

Exercise 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?




Exercise 3) IPX across frame relay

Objective: The objective of this exercise is to configure Brisbane and Canberra
for IPX connectivity across the frame relay service established in the initial
exercise. This network will use EIGRP/IPX as the routing protocol.

a) Configure IPX addressing on the loopback and frame relay interfaces of
Canberra and Brisbane. Use the following addressing:


Router Interface IPX network

Brisbane loop0 10
Brisbane s0 20
Canberra loop0 30
Canberra s0 20


b) Use a frame relay map statement to map between next hop IPX address
and DLSI on Brisbane and Canberra. Map DLCI 50 only. Do not use inverse
ARP.

c) Configure the network for EIGRP/IPX.

d) Configure a static SAP on loopback interface of Brisbane. Verify that it is

visible on Canberra.

e) Verify that Brisbane can IPX ping the loopback interface on Canberra.






Exercise 4) Appletalk across frame relay

Objective: The objective of this exercise is to configure Brisbane and Canberra
for Appletalk connectivity across the frame relay service established in the initial
exercise. For the sake of variety we will tunnel the Appletalk across the frame
relay cloud using generic route encapsulation (GRE) over IP.

a) Connect Brisbane and Canberra via a TCP/IP tunnel. Use the loopback
interfaces as tunnel endpoints.

b) Configure Appletalk (AT) cable-ranges and zones on the tunnel interfaces of
Brisbane and Canberra. Use GRE encapsulation. Appletalk does not work
on loopback interface so configure Appletalk on the ethernet0 interfaces
instead, but turn off keep alives to force the line protocol up.


Router Interface Cable range Zone

Brisbane ether0 10-10 QLD
Brisbane tunnel0 20-20 Australia
Canberra tunnel0 20-20 Australia

Canberra ether0 30-30 ACT


c) Verify that Brisbane can Appletalk ping the ethernet0 interface on Canberra,
and vice versa.
Exercise 5) DecNet across frame relay

Exercise 7) Troubleshoot your network

Objective: The objective of this exercise is to troubleshoot the network that you
have created so far. This is a simulation of what you will be asked to do at the
real CCIE lab.

a) Verify that you have end-to-end connectivity for IP, IPX, AT, DecNet and
Vines. This working network is now baseline.

b) Leave the room while your instructor inserts 6 trouble tickets into your
network.

c) When asked to return, troubleshoot your network and bring it back to
baseline. You have max 2 hours to complete this exercise.

While troubleshooting, document your approach. As an absolute minimum list
the problems you find, some suspected causes, and the actual fault once you
find it. At the CCIE lab you will be given credit for this documentation, even if
you do not manage to resolve all problems.



Exercise 8) DLCI prioritization

Objective: The objective of this exercise is to configure DLCI prioritization
between Brisbane and Canberra. Recall that 2 parallel DLCI’s connect these 2
routers. DLCI prioritization will control which traffic goes on which DLCI.

a) Now that you have regained full connectivity, configure DLCI prioritization on
both Brisbane and Canberra so that:


- Telnet traffic is given high priority.
- Traffic to TCP port ‘daytime’ is given low priority.
- Everything else is given medium priority.


b) Put high and medium traffic on DLCI 50. Put the normal and low traffic on
DLCI 51.

c) Verify your configuration by turning on ‘debug priority’ and ‘debug frame
relay packet’. From Brisbane telnet to the daytime port on Canberra (telnet
Canberra daytime). Examine the debug output to verify that traffic is sent
down DLCI 51 only when you telnet to daytime.
Exercise 9) STUN and X.25

Objective: The objective of this exercise is to configure X.25 between Brisbane
and Canberra. Because these 2 routers are separated by Sydney and
Melbourne we will configure Sydney and Melbourne to STUN the X.25 across.

a) Reconfigure the serial ports on Melbourne and Sydney for STUN. Tunnel in
basic mode between the 2 serial interfaces using TCP/IP encapsulation.


b) Reconfigure the serial0 interfaces on Brisbane and Canberra for X.25.
Canberra and Brisbane will appear as if they are running X.25 back to back,
so make Brisbane X.25 DCE.

c) Configure the X.25 interfaces with the following characteristics:


- Brisbane X.121 address is 11111
- Canberra X.121 address is 22222
- Use a single SVC to carry multiprotocol traffic (RFC-1356)
- Use virtual circuit number 53 as a two way multiprotocol SVC
- Incoming/outgoing packet size of 1024 bytes
- Incoming/outgoing window of 7


d) Add the necessary X.25 map statements to make the existing IP, IPX, AT,
DecNet and Vines configuration on the Canberra and Brisbane work across
the X.25 cloud. Use Multiprotocol encapsulation (RFP 1356)

e) Verify that IP, IPX, Appletalk, DecNet and Vines all work by pinging from
Brisbane to Canberra.


Exercise 10) Hot standby router protocol (HSRP)

Objective: The objective of this exercise is to configure HSRP on the Ethernet
connecting Sydney and Melbourne. HSRP is a hot feature that ensures that end
systems configured with a default gateway do not loose remote connectivity just
because their default router becomes unavailable.


a) Configure HSRP on Melbourne and Sydney. Hint: use the ‘standby’
command.

b) Configure Melbourne to become the active default gateway, by giving it a
better priority. Use ‘show standby’ to verify the result.

Exercise 11) Advanced BGP-4

Objective: The objective of this exercise is to configure an advanced BGP
network. This BGP network will connect 3 autonomous systems using external
BGP. Autonomous system 2 will also use internal BGP. By configuring a route
filter you will force a certain BGP route to be used to reach a specific network.
You will also configure route summarization, which in BGP is referred to as
Classless Inter Domain Routing (CIDR). Warning: BGP is a CCIE lab favorite.

a) Connect the 2 ethernet0 interfaces on Brisbane and Canberra.

b) Erase the existing configuration on all routers.

c) Give all 4 routers appropriate hostnames and passwords. Add clocking to
the appropriate serial interfaces.

Canberra Serial0 131.111.0.0 /16
Canberra Ethernet0 131.108.0.0 /16


e) Configure Internal BGP between Sydney and Melbourne. Configure External
BGP between Brisbane/Melbourne, Brisbane/Canberra and
Canberra/Sydney. Use the following autonomous system numbers:


Router Autonomous System

Brisbane 1
Melbourne 2
Sydney 2
Canberra 3


f) Because we have no interior routing protocol configured it is necessary to
add ‘no synchronization’ to the BGP configuration on Sydney and Melbourne.


g) Use ping to verify that you have full connectivity between all networks.

h) Configure route summarization o Brisbane so the 2 loopback interfaces are
advertised as one CIDR route. Suppress the non-summary routes.

i) Configure an input route filter on Melbourne so that Melbourne ignores the
BGP update from Brisbane advertising the loopback interfaces. This will
force Melbourne to use the second best route-to-route traffic to these
networks, i.e. send it via Sydney.

j) Verify that Melbourne now routes traffic to Brisbane’s loopback interface by
sending it via Sydney. Use ‘trace’ or examine the routing table.
Exercise 12) EIGRP

- RIP update interval is 120 seconds
- SAP pacing is 0 msec



d) Use ‘show ipx interface’ to verify that timers are set as expected.

e) Configure an IPX route filter on Sydney so ‘c0ffee’ is NOT advertised to
Canberra. Verify that Canberra is unable to IPX ping the ‘c0ffee’ network.

f) Configure an IPX static roué to ‘c0ffee’ on Canberra. Verify that Canberra is
able to IPX ping the ‘c0ffee’ network.
Exercise 14) Auto install
