Assigning IP Address in Cisco Router and Juniper Router (Cisco vs Juniper).


Assigning IP Address in Cisco Router and Juniper (Cisco vs Juniper).

This tutorial will help you to understand the difference between assigning IP address in cisco router and juniper router. Both Router has their own IOS so that the configuration also be difference.
So we will start by configure Cisco router then juniper router.


In cisco router for LAN  we are using network 192.168.1.0/24 and for say WAN IP 195.185.110.3/30 and in juniper side for  LAN 172.16.10.1/24 and for say WAN IP  103.195.11.3/30

Cisco Router:

For IP configuration, first we have to login router configuration mode. Then set all ip  addresses in interface and no shutdown command using for up the interface from administratively down because of by default router port is always administratively down. Finally save all changes or configuration by using command copy run start.

Router>
Router>enable
Router#
Router#configure terminal
Router(config)#        
Router(config)#interface fastethernet0/1        
Router(config-if)#ip address 192.168.1.1 255.255.255.0
Router(config-if)#description LAN interface - default gateway
Router(config-if)#no shutdown
Router(config-if)#exit

Router(config)#interface serial 0/0
Router(config-if)#ip add 195.185.110.3 255.255.255.252
Router(config-if)#no shutdown
Router(config-if)#clock rate 64000
Router(config-if)#description WAN interface connected to Internet/ISP
Router(config-if)#exit
Router(config)#end
Router#copy run start


Now we will go for configure Juniper router:


Juniper Router:

First, we will login configure mode by using command configure or edit.Then edit interface for LAN ge-1/1/0 and set ip address and then edit interface ge-1/0/1 for WAN and assign ip address and description. Finally save all configuration by using command commit.


# cli
 root@Router>
 root@Router> configure
[edit]
 root@Router# edit interfaces ge-1/1/0
[edit interfaces ge-1/1/0]
 root@Router# set description LAN interface - default gateway
[edit interfaces ge-1/1/0]
 root@R1# set unit 0 family inet address 172.16.10.1/24
[edit interfaces ge-1/1/0]

 root@Router# edit interfaces ge-1/0/1
[edit interfaces ge-1/0/1]
 root@Router# set description WAN interface connected to Internet/ISP
[edit interfaces ge-1/0/1]
 root@Router# set unit 0 family inet address 103.195.11.3/24
[edit interfaces ge-1/0/1]
 root@Router# commit
