Passive Interfaces

Now, typically in ISIS you make the loopback interface passive.

To make an interface passive, is very simple.

RP/0/7/CPU0:R1#conf t

Sun Apr 1 22:45:10.308 UTC

RP/0/7/CPU0:R1(config)#router isis LAB

Change to the interface uder the protocol

RP/0/7/CPU0:R1(config-isis)#int loop0

And set it as passive.

RP/0/7/CPU0:R1(config-isis-if)#passive

RP/0/7/CPU0:R1(config-isis-if)#commit

Authentication

Time to configure IS-IS authentication. Again, all this is done under the

routing process – makes keeping all relevant changes very close together.

RP/0/7/CPU0:R1(config)#router ISIS LAB

RP/0/7/CPU0:R1(config-isis)#inter g0/3/0/2

Now, to configure authentication we need to set the hello-password. As you

can see we have some options listed – but for this lab we will use hmac-md5.

RP/0/7/CPU0:R1(config-isis-if)#hello-password ?

WORD The unencrypted (clear text) hello password

accept Use password for incoming authentication only

clear Specifies an unencrypted password will follow

encrypted Specifies an encrypted password will follow

hmac-md5 Use HMAC-MD5 authentication

keychain Specifies a Key Chain name will follow

text Use cleartext password authentication

RP/0/7/CPU0:R1(config-isis-if)#hello-password hmac-md5 cisco

Now before we commit, let’s look at our neighbors

RP/0/7/CPU0:R1(config-isis-if)#do show isis neighbors

Sun Apr 1 22:49:07.800 UTC

IS-IS LAB neighbors:

System Id Interface SNPA State Holdtime Type IETF-NSF

GSR-R2 Gi0/3/0/2 00d0.7901.3a78 Up 7 L2 Capable

Total neighbor count: 1
