Option: Allowing Nonpacket GMPLS LSPs to Establish a Path Through JUNOS-Based Routers

When you configure a nonpacket LSP as administratively down, an external device (not a router running JUNOS Software) can either perform a Layer 1 path setup test or help bring up an optical cross-connect through a router running JUNOS Software.

To configure a nonpacket LSP as administratively down, you must set the A-bit in the ADMIN_STATUS field of a RSVP packet. This feature does not affect control path setup or data forwarding for packet LSPs.

To configure the ADMIN_STATUS field for a GMPLS LSP RSVP packet, issue the admin-down statement at the [edit protocols mpls label-switched-path lsp-name] hierarchy level or the [edit logical-systems logical-system-name protocols mpls label-switched-path lsp-name] hierarchy level.
