Which of the following are the default settings for the Alcatel-Lucent 7750 SR when using LDP?
The default settings for the Alcatel-Lucent 7750 SR when using LDP are ordered control mode and downstream unsolicited. In ordered control mode, LDP assigns labels to routes in a specified order, and downstream unsolicited refers to the method by which routers distribute labels to their peers without requiring a request.
LDP on the 7750 SR operates in downstream unsolicited, ordered control mode with liberal label retention. These parameters are fixed and cannot be modified.
Book: Designing and Implementing IP/MPLS-Based Ethernet Layer 2 VPN Services: An Advanced Guide for VPLS and VLL Chapter3: " In the Alcatel-Lucent Service Router Portfolio (ALSRP), when using LDP as the label distribution protocol, the label distribution mode is Downstream Unsolicited, Independent Control, with Liberal Retention. "
Correct Answer: D
Correct Answer: B. Ordered control mode; downstream unsolicited. LDP on the 7750 SR operates in downstream unsolicited, ordered control mode with liberal label retention. These parameters are fixed and cannot be modified.
• Downstream unsolicited, ordered control with liberal retention (method used by LDP) • Downstream on demand, ordered control with conservative retention (method used by RSVP-TE)
