Implementing MPLS Label Distribution Protocol
Purpose
Enters global configuration mode.
Enters MPLS LDP configuration mode.
Causes a router to advertise an explicit null label in situations where
it normally advertises an implicit null label (for example, to enable an
ultimate-hop disposition instead of PHOP).
commit—Saves the configuration changes and remains within the
configuration session.
end—Prompts user to take one of these actions:
• Yes— Saves configuration changes and exits the configuration
session.
• No—Exits the configuration session without committing the
configuration changes.
• Cancel—Remains in the configuration mode, without committing
the configuration changes.
(Optional)
Displays the MPLS LDP view of installed forwarding states (rewrites).
