bfd-enable
Syntax [no] bfd-enable
Context config>router>mpls>lsp>bfd
config>router>mpls>lsp>primary>bfd
config>router>mpls>lsp>secondary>bfd
Description This command enables S-BFD for an SR-TE LSP. The BFD template must be configured in
the config>router>bfd context before issuing the bfd-enable command.
The no form of this command disables S-BFD on the SR-TE LSP.
Default no bfd-enable
bfd-template
Syntax bfd-template name
no bfd-template
Context config>router>mpls>lsp>bfd
config>router>mpls>lsp>primary>bfd
config>router>mpls>lsp>secondary>bfd
Description This command specifies the BFD template to be used for an S-BFD session on an SR-TE
LSP. The BFD template is configured in the config>router>bfd context and defines the
parameters used during the session, such as the minimum transmit and receive intervals for
control packets.
The no form of this command removes the template.
Default no bfd-template
Parameters name — the name of the existing BFD template
failure-action
Syntax failure-action failover-or-down
no failure-action
Context config>router>mpls>lsp>bfd
Description This command configures the resulting action when BFD fails on an SR-TE LSP.
A failure action of failover-or-down means that a switchover from the active path is triggered
if the BFD session fails on the active path (primary or standby). If there is no available path
to switch to, the LSP is taken operationally down. This failure action is only applicable to SR-
TE LSPs.
