  For the following features described in the indicated sections of the RFC, the Junos OS supports one of the possible modes but not the other:

  • Label distribution control (section 2.6.1): Ordered mode is supported, but not Independent mode.
  • Label retention (section 2.6.2): Liberal mode is supported, but not Conservative mode.
  • Label advertisement (section 2.6.3): Downstream Unsolicited mode is supported, but not Downstream on Demand mode.
• RFC 3212, Constraint-Based LSP Setup using LDP
• RFC 3478, Graceful Restart Mechanism for Label Distribution Protocol
