Ensure BFD Authentication is Not Set to Loose-Check
Description
BFD Peers should be authenticated. Bidirectional Forwarding Detection (BFD) is a Forwarding Plane feature which allows more rapid detection of a failed neighbor then can be achieved through a routing protocols' normal detection mechanisms, providing faster reconvergence. Audited against the output of 'show configuration | display set | no-more' (set format, not the curly-brace hierarchy).
How it is checked
Audit method: Configuration pattern
- Pattern
(?m)^set [^\n]*\bbfd-liveness-detection authentication loose-check\b
How it is fixed
Fix method: Guidance or infrastructure patch
! If you have deployed BFD with Loose Authentication Checking, it can be disabled by issuing the appropriate [.* bfd-liveness-detection] hierarchy, in this example we are configuring BFD Authentication for BGP: delete protocols bgp bfd-liveness-detection authentication loose-check BFD may be configured at a wide variety of configuration hierarchies, for different Protocols, Routing Instances or even for Static Routes. The bfd-liveness-detection hierarchy is the same at each level it is used, so the Remediation Process is the same and should be applied at each hierarchy indicated in the Audit Procedure.
