LSNDI RMRA Lab Work
EIGRP
Today's task:
Setup the network as shown in the diagram to route using EIGRP. Use
Packet Tracer 5.x to achieve this.
(note this lab works in PT 4.1)
Draw a diagram
with ALL pertinent information before you begin configuration.
Use addressing from the block 192.168.1.0 /28 for the serial interfaces
on all routers.
Use 22.22.22.0 /24 for the LAN on Paris.
Use 33.33.33.0 /24 for the LAN on London.
Use 200.0.0.0 /24 for the LAN on Core2.
Make sure all routers are named correctly both on the diagram and
within the IOS.
Check connectivity on all interfaces before beginning the routing part
of this lab work.
When you can ping all interfaces from a neighbour router, begin
configuring EIGRP.
Configuring
EIGRP
EIGRP needs an Autonomous System Number (ASN) to identify the
part of the network to which the routing information will relate.
Use an ASN that you have made up. The number will lie in the range 1 to
65535
Use this number for all routers in your network.
The syntax for setting up EIGRP for routing is as follows. 123 has been used as the ASN.
Router(config)#router
eigrp 123
Router(config-router)#network
192.168.1.8
Router(config-router)#network a.b.c.d
Router(config-router)#network e.f.g.h
etc. etc.
Add all connected networks to your EIGRP
network statements for each of the 4 routers in the network.
Routing Information
Use the show
ip route command on all 4 routers to view all 4 routing tables.
Copy the tables into a word document and save the document.
Make a note against the routing table that these are before bandwidth
has been configured.
Bandwidth
configuration
When configuring
serial links
using EIGRP, it is important to configure the bandwidth setting on the
interface. If the bandwidth for these interfaces is not changed, EIGRP
assumes
the default bandwidth on the link instead of the true bandwidth. If the
link is
slower, the router may not be able to converge, routing updates might
become
lost, or suboptimal path selection may result. To set the interface
bandwidth,
use the following syntax:
router(config-if)#bandwidth
[kilobits]
For our network
we will setup the serial link between London and Paris as 56kbps and
the rest of the serial links as 1000 kbps. This ought to have the
effect of forcing all traffic to use the Core1 and Core2 routers.
Routing
Tables
Use the show
ip route command again on all 4 routers to view all 4 routing
tables. Copy the tables into the word document you created earlier and
save the document.
Make a note against the routing table that these are after bandwidth
has been configured.
What differences are there between the routing tables before and after bandwidth
has been configured?
Note the difference(s) by highlighting the changes in the Word document.
Save this document and keep it
securely.
