Cisco IOS XR Routing Configuration Guide

Step 3

lsp-password {hmac-md5 | text} {clear |

encrypted}

password

[level {1 | 2}] [send-only]

[snp send-only]

Example:

RP/0/RP0/CPU0:router(config-isis)# lsp-password

hmac-md5 encrypted password1 level 1

Configures the LSP authentication password.

• The hmac-md5 keyword specifies that the password is

used in HMAC-MD5 authentication.

• The text keyword specifies that the password uses

cleartext password authentication.

• The clear keyword specifies that the password is

unencrypted when entered.

• The encrypted keyword specifies that the password is

encrypted using a two-way algorithm when entered.

• The level 1 keyword sets a password for authentication

in the area (in Level 1 LSPs and Level SNPs).

• The level 2 keywords set a password for authentication

in the backbone (the Level 2 area).

• The send-only keyword adds authentication to LSP and

sequence number protocol data units (SNPs) when they

are sent. It does not authenticate received LSPs or

SNPs.

• The snp send-only keyword adds authentication to

SNPs when they are sent. It does not authenticate

received SNPs.

Note To disable SNP password checking, the snp

send-only keywords must be specified in the

lsp-password command.

Step 4

interface

type instance

Example:

RP/0/RP0/CPU0:router(config-isis)# interface

POS 0/1/0/3

Enters interface configuration mode.
