Day 3:
ROUTING FUNDAMENTALS
- Routing Fundamentals:
By completing this lab, you will perform the following tasks:
Configure and verify proper operation of network interfaces.
Configure and monitor static routing
Configure and monitor OSPF.
In this part you will configure the device hostnames, root password, the
management network interface details including definition of specific services
allowed for accessing the device.
+ Configure root password on every device with the value of
labmentor123.
+ Based on the topology diagram configure the management and loopback
interfaces on each device with the IP address as listed in the table below:
Device Management IP Loopback IP WAN address
R1 192.168.1.10/24 192.168.1.100/24 15.0.0.1/24
R2 10.1.42.10/24 10.1.42.100/24 15.0.0.2/24
http: // w w w . L a b M e n t o r . o r g LABMENTOR
+ The management interface on each device needs to be used purely only
for management access and wont accept any transit traffic. In addition this
interface will accept only specific services as defined in the table below
Device Hostname
R1 (SRX) ssh with allowed root access, telnet, http, https
R2 (SRX) ssh with allowed root access, telnet, http, https
Login as user root with the password labmentor123:
Issue the show route command to display the contents of the route table:
root@R1> show route
root@R1> show route all
Issue the show interfaces terse command to verify the current state of the
recently configured interfaces:
root@R1> show interfaces terse
http: // w w w . L a b M e n t o r . o r g LABMENTOR
This case we will changes Fe_0/0/0 = em0, Se_0/0/2 = em1.
Enter configuration mode and navigate to the [ edit interfaces ] hierarchy level:
root@R1> configure
root@R1# edit interfaces
root@R1# set lo0 unit 0 family inet address 192.168.1.100/24
root@R1# set em0 unit 0 family inet address 192.168.1.10/24
root@R1# set em1 unit 0 family inet address 15.0.0.1/24
root@R1# commit
http: // w w w . L a b M e n t o r . o r g LABMENTOR
Issue the show interfaces terse command to verify the current state of the
recently configured interfaces:
root@R1# run show interfaces terse
The configured interfaces should all show Admin and Link states of up, as show
in the previous output. If the configured interfaces are in the down state, contact
your instructor (Khiem Bui).
http: // w w w . L a b M e n t o r . o r g LABMENTOR
Issue the show route command to view the current route entries:
root@R1# run show route
Note:
http: // w w w . L a b M e n t o r . o r g LABMENTOR
Now We use the ping utility to verify reachability to the neighboring devices
connect to your device:
root@R2# run ping 192.168.1.10
What does the result from the ping?

Configure the Static route on the Router R1:
root@R1# set routing-option static route 10.1.42.0/24 next-hop 15.0.0.2
roo@R1# commit
Configure the Static route on the Router R2:
root@R2# set routing-option static route 192.168.1.0/24 next-hop 15.0.0.1
roo@R2# commit
Verifying command:
root@R1# run ping 10.1.42.100
http: // w w w . L a b M e n t o r . o r g LABMENTOR
root@R1# run show route
root@R1# run show route protocol static
http: // w w w . L a b M e n t o r . o r g LABMENTOR
root@R1# run show configuration
root@R1# run show interfaces terse
http: // w w w . L a b M e n t o r . o r g LABMENTOR
- Configure and monitor OSPF
In this part, you will configure and monitor OSPF. You will configure a single
OSPF area based on the network diagram for this lab. Finally, you will perform
some verification tasks to that OSPF work properly.
In this part you will configure the device hostnames, root password, the
management network interface details including definition of specific services
allowed for accessing the device.
+ Configure root password on every device with the value of
labmentor123.
+ Based on the topology diagram configure the management and loopback
interfaces on each device with the IP address as listed in the table below:
Device Management IP Loopback IP WAN address
R1 192.168.1.10/24 192.168.1.100/24 15.0.0.1/24
R2 10.1.42.10/24 10.1.42.100/24 15.0.0.2/24
This case we will changes Fe_0/0/0 = em0, Se_0/0/2 = em1.
http: // w w w . L a b M e n t o r . o r g LABMENTOR
Enter configuration mode and navigate to the [edit protocols ospf] hierarchy
level:
root@R1> configure
root@R1# edit protocols ospf
Define OSPF area 0 and include all internal interfaces that connect to the remote
teams device and the directly connected virtual router:
root@R1# set area 0 interface em0
root@R1# set area 0 interface em1
root@R1# set area 0 interface lo0
root@R1# show
http: // w w w . L a b M e n t o r . o r g LABMENTOR
root@R2# set area 0 interface em0
root@R2# set area 0 interface em1
root@R2# set area 0 interface lo0
root@R2# show
Activate the candidate configuration using the commit command:
root@R1# commit
Issue the run show ospf neighbor command to veriry OSPF neighbor
adjacency state information:
root@R1# run show ospf neighbor
http: // w w w . L a b M e n t o r . o r g LABMENTOR
root@R2# run show ospf neighbor
If you do not see this state after several minutes, check with the remote team and
with your instructor, if need. Good luck
Issue the run show route protocols ospf to view the active OSPF routes in
your devices route table:
root@R1# run show route protocols ospf
root@R2# run show route protocols ospf
http: // w w w . L a b M e n t o r . o r g LABMENTOR
Delete all static routes used for internal connectivity:
root@R2# top edit routing-options
root@R2# show
root@R2# delete static route 192.168.1.0/24
root@R2# show
root@R2# commit and-quit
http: // w w w . L a b M e n t o r . o r g LABMENTOR
Now, activate the configuration and return to operational mode. Issue the show
route protocol ospf command to verify that the OSPF routes are now active:
Ping all internal devices to verify reachability through the OSPF router:
http: // w w w . L a b M e n t o r . o r g LABMENTOR
Do the ping tests succeed?
