Backup Tunnel If the Outbound FRR state is Ready or Active, this field indicates the
following:
• Which backup tunnel has been selected for this LSP to use in case
of a failure.
• The inbound label that will be prepended to the LSP’s data packets
for acceptance at the backup tunnel tail (the merge point).
Bkup Sender Template If the Outbound FRR state is Ready or Active, SENDER_TEMPLATE
an
d FILTERSPEC objects are shown. These objects will be used in
RSVP messages sent by the backup tunnel if or when the LSP starts
actively using the backup tunnel. They differ from the original
(prefailure) objects only in that the node (the PLR) substitutes its own
IP ad
dress for that of the original sender. For example, path and
pathTear messages will contain the new SENDER_TEMPLATE. Resv
and resvTear messages will contain the new FILTERSPEC object. If
this LSP begins actively using the backup tunnel, the display changes.
Bkup FilerSpec If the Outbound FRR state is Ready or Active, SENDER_TEMPLATE
an
d FILTERSPEC objects are shown. These objects will be used in
RSVP messages sent by the backup tunnel if or when the LSP starts
actively using the backup tunnel. They differ from the original
(prefailure) objects only in that the node (the PLR) substitutes its own
IP ad
dress for that of the original sender. For example, path and
pathTear messages will contain the new SENDER_TEMPLATE. Resv
and resvTear messages will contain the new FILTERSPEC object. If
this LSP begins actively using the backup tunnel, the display changes.
Path ID handle Protection Switch Byte (PSB) identifier.
Incoming policy Policy decision of the LSP. If RSVP policy was not granted for the
i
ncoming path message for the tunnel, the LSP does not come up.

Status For FRR LSPs, valid values are:
• Proxied—Headend routers
• Proxied Terminated—Tailend routers
For midpoint routers, the field always is blank.
