Chapter 9 Configuring IS-IS
Configuring IS-IS
SUMMARY STEPS
1. config t
2. interface interface-type slot/port
3. isis authentication-type {cleartext | md5} {level-1 | level-2}
4. isis authentication key-chain key {level-1 | level-2}
5. isis authentication-check {level-1 | level-2}
6. copy running-config startup-config
DETAILED STEPS
The following example shows how to configure cleartext authentication on an IS-IS instance:
switch# config t
switch(config)# interface ethernet 1/2
switch(config-if)# isis authentication-type cleartext level-2
switch(config-if)# isis authentication key-chain ISISKey
switch(config-if)# copy running-config startup-config
Command Purpose
Step 1
config t
Example:
switch# config t
switch(config)#
Enters configuration mode.
Step 2
interface
interface-type slot/port
Example:
switch(config)# interface ethernet 1/2
switch(config-if)#
Enters interface configuration mode.
Step 3
isis authentication-type {cleartext |
md5} {level-1 | level-2}
Example:
switch(config-if)# isis
authentication-type cleartext level-2
Sets the authentication type for IS-IS on this interface
as cleartext or as an MD5 authentication digest.
Step 4
isis authentication key-chain
key
{level-1 | level-2}
Example:
switch(config-if)# isis
authentication-key ISISKey level-2
Configures the authentication key used for IS-IS on
this interface.
Step 5
isis authentication-check {level-1 |
level-2}
Example:
switch(config-if)# isis
authentication-check
Optional) Enables checking the authentication
parameters in a received packet.
Step 6
copy running-config startup-config
Example:
switch(config-if)# copy running-config
startup-config
(Optional) Saves this configuration change.
