#create_ar(nic, with_id = false, ipv4 = nil, ipv6 = nil) ⇒ Object

Create AR

  • in case of IPv6 we use a standard PREFIX_LENGTH = 64

  • if we pass ipv4 we force nic use that IPv4

  • if we pass ipv6 we force nic use that IPv6

Parameters:

  • nic (object) —

    contains properties of the nic

  • with_id (Boolean) (defaults to: false) —

    determine if AR will contains AR_ID

  • ipv4 (string) (defaults to: nil) —

    create the AR with a IPv4 address

  • ipv6 (string) (defaults to: nil) —

    create the AR with a IPv6 address

Returns:

  • ar_tmp
