IPv6 considerations

For IPv6, all interfaces are defined to OMPROUTE by name only, and name wildcards are supported. This greatly simplifies definition considerations for OMPROUTE and VIPA interfaces.

To define IPv6 interfaces to OMPROUTE, you must know their names. Unlike IPv4, in which VIPA link names are generated by the stack, you specify link names to TCP/IP when defining IPv6 dynamic VIPA interfaces. These link names should be used when defining the same interfaces to OMPROUTE.

Tip: Using consistent naming conventions and name wildcards can make this task easier. For example, if you require that all IPv6 VIPA link names start with the letter V, and do not allow other interface types to have link names starting with V, a single definition can define all IPv6 VIPA interfaces to OMPROUTE as follows:

IPV6_OSPF_INTERFACE
      NAME=V*;

Unlike IPv4, there are no size limitations on the number of IPv6 dynamic VIPA addresses that OMPROUTE can advertise. In IPv6 OSPF, OMPROUTE will advertise all host and prefix addresses associated with owned interfaces, including VIPAs and dynamic VIPAs. In IPv6 RIP, sending and receiving of host routes should be turned on to allow host addresses associated with VIPAs to be advertised.
