Routing

Hi Experts

I have multiple areas in my routing domain and I want to configure inter area TE LSP. I read there are couple of options to do so like LSP stiching, LSP tunneling and contigous LSP. I am wondering how to configure these options in JUNOS. I would appreciate if any one can give me the link for do this or any configuration example.

Thanks

Take a look at the JNCIE-M Study Guide.

Hi,

You can refer below for different options that can be used for Inter-Area TE LSP

LSP tunneling Option:

http://www.juniper.net/techpubs/en_US/junos10.4/topics/usage-guidelines/mpls-configuring-a-hierarchy-of-rsvp-lsps.html

LSP Stitching:

http://www.juniper.net/techpubs/en_US/junos10.4/topics/usage-guidelines/mpls-configuring-lsp-stitching-cross-connects-using-ccc.html

The other option (which I feel is the easiest way) is to include "inter-domain" option in LSP configs

suryak@sammy# show protocols mpls

label-switched-path sammy-murano {
    to 4.4.4.4;
    inter-domain;
}

Hope this helps

Thanks but LSP tunneling option link has nothing about LSP tunneling

Hi,

I have provided an example for LSP Tunneling (LSP Hierachy) in the attached file with configurations.

Hope this helps

If you liked it, Kudos would be appreciated.

Dear Surya:

  After some test only the command "inter-domain" can enable inter-area LSP up. (but expand-loose-hop not works...)

But I can't find the related juniper configuration guide discuss about this.

Could you show me the reference documents about this command "inter-domain", thanks!
