Option: Selecting the Peer Model or the Overlay Model for GMPLS

Juniper Networks supports both the peer model and the overlay model for GMPLS. To implement the peer model, perform the following configuration tasks:

• Use the default CSPF calculation that is inherent in MPLS LSPs.
• Include a TE link and a control channel within the peer statement at the [edit protocols link-management] hierarchy level.
• Reference the peer-interface in both OSPF and RSVP.
• Configure OSPF and OSPF traffic engineering to connect with the OXC.
• Optionally, define a GMPLS LSP path.

To implement the overlay model, perform the following configuration tasks:

• Disable CSPF by including the no-cspf statement at the [edit protocols mpls label-switched-path lsp-name] hierarchy level.
• Define a strict GMPLS LSP data path to the remote OXC peer.
• Include a TE link and a control channel within the peer statement at the [edit protocols link-management] hierarchy level.
• Reference the peer-interface in RSVP.
