Functions

func BaseRouteAttrs added in v0.11.0 

func BaseRouteAttrs(p *config.PolicyConfig) model.RouteAttrs

BaseRouteAttrs returns the attributes from the announce block: the base prepend and communities carried by every announcement of the VIP.

func Evaluate 

func Evaluate(healthy bool, lowerPriorityFilePresent bool, p *config.PolicyConfig) model.VIPState

func RouteAttrsFor added in v0.11.0 

func RouteAttrsFor(p *config.PolicyConfig, state model.VIPState) model.RouteAttrs

RouteAttrsFor returns the BGP attributes to originate the VIP with in the given state:

  • announced: the announce block (base prepend + communities)
  • pessimized: base prepend + lower_priority prepend, and the union of both community lists, so a degraded node never outranks a healthy node with a larger base prepend
  • withdrawn: zero value (no route)
