    Hi community

     

    I am trying to deploy a POC on a customer MPLS network, the IGP is ISIS and it is using LDP. Everything was fine until I want to start configuring the ISIS, the authentication on the former device (Huawei) is set with a password with 24 characters and one of them is a quotetion mark (") so I can't configure it on my router, so sad. It is configured in a domain way in the customer network so I can't change it. Can you help me? It is an important oportunity to migrate their network to Juniper routers.

     

    Regards

    Hello,

    You need to escape " with backslash \:

     

    [edit protocols isis]
    regress@VMX# set level 2 authentication-key test\"123 
    
    [edit protocols isis]
    regress@VMX# commit 
    commit complete
    
    [edit protocols isis]
    regress@VMX# show 
    level 1 disable;
    level 2 {
        authentication-key "$9$gN4UHf5F/A0z3/CtpB17-dsoJ"; ## SECRET-DATA

    You can reverse-decrypt the above key online to be 100% sure. Here is the output from one of such tools:

     

    https://www.m00nie.com/juniper-type-9-password-tool/

     

    You chose to decrypt
    Your original string was $9$gN4UHf5F/A0z3/CtpB17-dsoJ
    Output text is test"123

    HTH

    Thx

    Alex

    Is there any official documentation of the allowed characters that can be used on the isis password?

     

    Regards

    Hi,

     

    key—Authentication password. The password can be up to 1024 characters long. Characters can include any ASCII strings. If you include spaces, enclose all characters in quotation marks (“ ”).
