Configuring Bfd At The Tail End; Configuring Bfd Over Lsp Sessions On Line Cards - Cisco NCS 6000 Series Configuration Manual

Implementing BFD

Configuring BFD at the Tail End

Use the tail end global configuration commands to set the BFD minimum-interval and BFD multiplier
parameters for all BFD over LSP sessions. The ranges and default values are the same as the BFD head end
configuration values. BFD will take the maximum value set between head end minimum interval and tail end
minimum interval.
Perform these tasks to configure BFD at the tail end.

Configuring BFD over LSP Sessions on Line Cards

BFD over LSP sessions, both head-end and tail-end, will be hosted on line cards with following configuration
enabled.
SUMMARY STEPS
1. configure
2. bfd
3. multipath include location node-id
4. commit
Purpose
Configures hello interval in milliseconds.
Hello interval range is 100 to 30000 milliseconds. Default
hello interval is 100 milliseconds
Configures BFD multiplier detection.
BFD multiplier detect range is 3 to 10. Default BFD
multiplier is 3.
