simtime_t IPv6InterfaceData::_getMaxInitialRtrAdvertInterval (  )  [inline]

Getters/Setters for all variables and constants defined in RFC 2461/2462 can be found here. Operations responsible for protocol constants are marked with a "_" prefix. Constants in this class are stored as instance variables. Default values for certain variables are defined at the top of this file, while certain variables have to be generated. Protocol constants are subject to change as specified in RFC2461:section 10 depending on different link layer operation. Getters and setters have been implemented for protocol constants so that a wireless interface may be set to a different set of constant values. (ie. changed by the FlatNetworkConfigurator) Such a design allows both wired and wireless networks to co-exist within a simulation run.
