Out intf/label Out interface—short name of the physical interface through which traffic
goes to the protected link.
Out label:
• At a tunnel head, this is the label advertised by the tunnel destination
device. The value “Untagged” occurs when no such label has been
advertised.
• At tunnel midpoints, this is the label selected by the next hop device. The
“Pop Tag” value occurs when the next hop is the tunnel’s final hop.
FRR intf/label Fast Reroute interface—the backup tunnel interface.
Fast Reroute label:
• At a tunnel head, this is the label selected by the tunnel tail to indicate
the destination network. The value “Untagged” occurs when no such
label has been advertised.
• At tunnel midpoints, this has the same value as the Out Label.
Status State of the rewrite: partial, ready, or active. (These terms are defined above
in
the “Syntax Description” section).
