Title: Re: [MPLS-OPS]: Juniper MPLS

Hi Hernan,

You need a few steps dependent on signalling you will use:

1. Add “family mpls” to all the interfaces for which you would like to conduct MPLS
2. Add interfaces to “edit protocols mpls”
3. Add interfaces to either “edit protocols rsvp” or “edit protocols ldp”
   

If you use RSVP then under “edit protocols mpls” you need to define your LSP.. You will name the LSP and include the egress or destination IP address of the LSP (normally loopback).

By default Junos lsps go into inet.3 and are only used if you have BGP routes whose protocol next hop recurses to an LSP destination endpoint in this inet.3 table.  So if you have BGP routes and the next-hop for those routes is a loopback that you build an LSP to then traffic will enter the LSP towards that next-hop.

Hope this helps.

If it is just setting up an LSP from point A to point Z, well, that is pretty simple. If you are wanting to setup 2547 VPNs, that isn't difficult either, but requires a bit more work and understanding of MPLS and BGP, for example.
