Hi all,
I have a question about MPLS configuration
I have setup a simple lab for this in my MX80
CE1---R1---R2---CE2
On R1, R2, I use ospf for the igp and advertise the lo0 to each other. iBGP for signaling and RSVP MPLS on top of it.
I manually configure the LSP and everything is fine because I just simply copy the config from Juniper KB.
However, the LSP was down after the above setup.
I found some passage and configure no-cspf under protocol mpls. After that, all connection goes up.
I am wondering why no-cspf will bring the connection up. Do I need to configure this once I manually configure the LSP? CSPF can be enabled if let the router calculate the LSP?
Thanks!
