Integrated IS-IS
### IS-IS BASIC CONFIGURE
## 1, BASIC CONFIG, HOSTNAME, IP ADDRESS ACCORDING TO THE DIAGRAM.
# R1: HOSTNAME R1
enable
config terminal
hostname R1
line console 0
loggin synch
no exec-timeout
no ip domain-lookup
line console 0
privilege level 15
no login
line vty 0 4
privilege level 15
no login
end
wr
=====================================
# R2: HOSTNAME R2
enable
config terminal
hostname R2
line console 0
loggin synch
no exec-timeout
no ip domain-lookup
line console 0
privilege level 15
no login
line vty 0 4
privilege level 15
no login
end
wr
=====================================
# R3: HOSTNAME R3
enable
config terminal
hostname R3
line console 0
loggin synch
no exec-timeout
no ip domain-lookup
line console 0
privilege level 15
no login
line vty 0 4
privilege level 15
no login
end
wr
=====================================
## 2 CONFIGURE IP ADDRESS ACCORDING TO THE DIAGRAM
# R1:
config terminal
interface f0/0
ip address 172.16.0.1 255.255.255.0
no shutdown
exit
interface loopback 0
ip address 192.168.10.1 255.255.255.0
end
wr
=======================================================
# R2:
config terminal
interface f0/0
ip address 172.16.0.2 255.255.255.0
no shutdown
exit
interface loopback 0
ip address 192.168.20.2 255.255.255.0
end
wr
=======================================================
# R3:
config terminal
interface f0/0
ip address 172.16.0.3 255.255.255.0
no shutdown
exit
interface loopback 0
ip address 192.168.30.3 255.255.255.0
end
wr
=======================================================
## 3 CONFIGURE INTERGRATED IS-IS
# R1
config terminal
router isis
net 49.0001.1111.1111.1111.00
exit
interface f0/0
ip router isis
isis priority 100
interface loopback 0
ip router isis
end
wr
==================================================================
# R2
config terminal
router isis
net 49.0001.2222.2222.2222.00
exit
interface f0/0
ip router isis
isis priority 100
interface loopback 0
ip router isis
end
wr
==================================================================
# R3
config terminal
router isis
net 49.0001.3333.3333.3333.00
exit
interface f0/0
ip router isis
isis priority 100
interface loopback 0
ip router isis
end
wr
==================================================================
## 3 VERIFYING IS-IS ADJACENCIES AND OPERATION
# show ip protocols
# show clns protocols
# show clns neighbors
# show clns neighbors detail
# show isis database
# show clns interface f0/0
# show isis database R1.00-00 detail
# show isis topology
# show ip route
==================================================================
## 4 CONVERTING TO THE IS-IS BACKBONE
# R1
config terminal
router isis
is-type level-2-only
end
wr
==================================================================
# R2
config terminal
router isis
is-type level-2-only
end
wr
==================================================================
# R3
config terminal
router isis
is-type level-2-only
end
wr
==================================================================
## 5 IMPLEMENTING IS-IS L2 CORE AUTHENTICATION
# R1
config terminal
interface f0/0
isis password 123 level-2
end
wr
=================================================================
# R2
config terminal
interface f0/0
isis password 123 level-2
end
wr
=================================================================
# R3
config terminal
interface f0/0
isis password 123 level-2
end
wr
=================================================================
# debug isis adj-packets
=================================================================
## 5 IMPLEMENTING IS-IS DOMAIN AUTHENTICATION
# R1
config terminal
router isis
domain-password 123
end
wr
==================================================================
# R2
config terminal
router isis
domain-password 123
end
wr
==================================================================
# R3
config terminal
router isis
domain-password 123
end
wr
