Configuring Is-Is Interface-Specific Parameters; Configuring Authentication - Juniper IGP - CONFIGURATION GUIDE V11.1.X Configuration Manual

JUNOSe 11.0.x IP, IPv6, and IGP Configuration Guide

Configuring IS-IS Interface-Specific Parameters

You can change IS-IS interface–specific parameters; most can be configured
independently of other attached routers. You are not required to alter any interface
parameters; however, some parameters must be consistent across all routers in your
network. If you change certain values from the defaults, you must configure them
on multiple interfaces and routers.
In the following command guidelines, many parameters are preset to a default value.
If that parameter has been modified from its default, use the no version of the
command to restore its default value.

Configuring Authentication

You can set a password to authenticate IS-IS hello packets, and you can configure
HMAC MD5 authentication for IS-IS interfaces.

Configuring IS-IS Interface-Specific Parameters
host1(config-if)#interface fastEthernet 1/0
host1(config-if)#ipv6 address 2008::1/48
host1(config-if)#ipv6 router isis floor12
host1(config)#router isis floor12
host1(config-router)#net 47.0010.0000.0000.0000.0001.0001.1111.1111.1111.00
host1(config-router)#address-family ipv6 unicast
host1(config-router-af)#redistribute ospf level-1-2
host1(config-router-af)#redistribute isis level-2 into level-1
host1(config-router-af)#distribute-domain-wide
host1(config-router-af)#summary-prefix 2001:2000::0/8 level-1 metric 10 tag 100
host1(config-router-af)#table-map ospfFilter
Use to specify a password associated with an interface for authentication of IS-IS
hello packets, and to enable simple authentication of level 1 or level 2 hello
packets.
You can specify whether the password is for level 1 or level 2 hellos.
Example
host1(config-if)#isis authentication-key 0 red5flower6
Use the no version to delete the password.
See isis authentication-key
Use to configure HMAC MD5 authentication for an interface, and to enable MD5
authentication of level 1 or level 2 hello packets.
Generates a secure, encrypted message digest of level 1 or level 2 hello packets
and inserts the digest into the packet from which it is created. Level 1 is the
default.
You can specify whether the key is entered in unencrypted or encrypted format.
If you do not specify which, the string is assumed to be unencrypted.
