def self.afi_cli(afi)
  # Add ipv6 support later
  fail ArgumentError, "Argument afi must be 'ipv4'" unless
    afi[/(ipv4)/]
  afi[/ipv4/] ? 'ip' : afi
end

.pims ⇒ Object

self.pims returns a hash of all current pim objects. There will be one object for each vrf. This method has slightly different behavior than most of the other “get all objects” methods because the pim properties are standalone and do not reside in a “pim” container; therefore, this method simply returns a pim object for each vrf regardless of whether there are any specific pim properties currently defined for the context.

def default_bfd
  config_get_default('pim', 'bfd')
end

#destroy ⇒ Object

This destroy method is different than most because pim does not have a “container” for properties, they simply exist in a given vrf context. For that reason destroy needs to explicitly set each property to its default state.
