configure isis area area-password

configure isis area area_name area-password [none | [encrypted simple encrypted_password | simple {password} ] {authenticate-snp {tx-only}}]


This command sets or clears the password for level 1 LSPs.

Syntax Description

area_name Specifies the router process to which the password configuration applies.
none Disables level 1 password authentication.
encrypted simple password Enables password authentication and specifies that the supplied password is encrypted and must be decrypted prior to placement in a TLV.
authenticate-snp tx-only Enables password authentication and level 1 SNP authentication. If the tx-only keyword is specified, the password is included in SNPs on transmission, but received SNPs are not authenticated.



Usage Guidelines

Only plain text passwords are supported. Passwords may be up to 254 alphanumeric characters in length. Although passwords are plaintext in the protocol, they are displayed and saved in an encrypted form.

When password authentication is enabled, received packets are authenticated against the configured password and are discarded if the password does not match. Authentication TLVs are included in transmitted level 1 LSPs with a configured password.
