4) The data flow is on the primary LSP if both the primary and secondary LSPs in one
protection group fail.
When the primary LSP is in the up/no-defect state and the secondary LSP is in the
down, in-defect, or down/in-defect state, the data flow is on the primary LSP. If the
primary LSP then turns into the down, in-defect, or down/in-defect state, no
switching will take place.
When the primary LSP is in the down, in-defect or down/in-defect state and the
secondary LSP is in the up/no-defect state, the data flow is on the secondary LSP.
If the secondary LSP then turns into the down, in-defect, or down/in-defect state,
the data flow will be switched to the primary LSP though the latter is not
operational.
5) When you delete a protection group where the data flow is on the secondary LSP,
the data flow will be switched to the primary LSP before the group is deleted, even
if the primary LSP is not operational.
6) If no protection group is configured, the manually-configured secondary LSP will
not have a corresponding LSP forwarding entry.
II. Configuration Procedure
Follow these steps to configure a protection group:
Enter system view
Configure a protection
group for the specified
primary LSP
Enable external protection
switch
Display information about
the protection group
