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?
