Support For Bfd Failure Action With Sr-Te Lsps - Nokia 7705 SAR-W Series Manual

MPLS and RSVP-TE
When S-BFD is configured at the LSP level, separate S-BFD sessions with the same
configuration are enabled on all primary, secondary, and standby paths of the LSP.
Alternatively, S-BFD can be configured on the primary path or secondary path of the
LSP, as follows:
configure>router>mpls>lsp <name> sr-te
configure>router>mpls>lsp <name> sr-te
The wait-for-up-timer command only applies if the configured failure action is
failover-or-down. For more information, see
SR-TE
3.12.6.2
S-BFD provides a mechanism to check the data path forwarding for an SR-TE LSP.
If an S-BFD session fails, the LSP can be brought operationally down when the
failure-action command is configured with the failover-or-down option. When the
failure-action command is not configured, an S-BFD failure will only raise a trap.
The failure-action command is available in the following context:
configure>router>mpls
The failure-action command is configured at the LSP level. It can be configured
whether S-BFD is applied at the LSP level or the individual path level. The failure-
action command can be configured even if the BFD template is not yet configured.
