    Understanding IPv6 Protocol Parameters

    The MobileNext Broadband Gateway supports a series of parameters relating to IPv6 router advertisement.

    Some of the most important pieces of IPv6 are built into the way the IPv6 protocol handles routers (or, in this case, the broadband gateway). Instead of requiring the user to configure a default router address, as typical in IPv4 configuration, IPv6 lets routers advertise their presence to other devices on the subnet. This allows hosts to choose the router that is most natural for the application.

    You can configure several parameters for a gateway that determine how the IPv6 router protocols operate:

    • hop limit—The number of hops used in the router advertisements. A value of zero means routers will not readvertise router availability.
    • maximum advertisement interval—The maximum interval the router can wait before sending a router advertisement.
    • minimum advertisement interval—The minimum interval the router can wait before sending a router advertisement.
    • maximum initial advertisement interval—The maximum interval the router can wait between initial router advertisements.
    • maximum initial advertisements—The maximum number of initial router advertisements.
    • reachable time—The value used in the reachable time field of the router advertisements.
    • router lifetime—The value used in the router lifetime field of the router advertisements.
    • retransmission timer—The value used in the retransmit timer field of the router advertisements.
