MPLS and RSVP

• The specified new-path-name value does not correspond to a previously defined path.
• The specified new-path-name value exists but is being used by any path of the same LSP, includ-
ing this one.
When you execute this command, MPLS performs the following procedures:
• MPLS performs a single MBB attempt to move the LSP path to the new path.
• If the MBB is successful, MPLS updates the new path
– MPLS writes the corresponding NHLFE in the data path if this path is the current backup path
for the primary.
– If the current path is the active LSP path, it will update the path, write the new NHLFE in the
data path that will cause traffic to switch to the new path.
• If the MBB is not successful, the path retains it current value.
• The update-path MBB has the same priority as the manual re-signal MBB.
resignal
Syntax resignal {lsp lsp-name path path-name | delay minutes}
Context tools>perform>router>mpls
