about Selecter Parameter
Hello everybody,
I would like to ask about selector in RFC2401.
In RFC2401;
>
> 4.4.2 Selectors
> .....
> - Destination IP Address (IPv4 or IPv6): this may be a single IP
> address (unicast, anycast, broadcast (IPv4 only), or multicast
> group), a range of addresses (high and low values (inclusive),
> address + mask, or a wildcard address. The last three are used
> .....
> transport'd packet, there will be only one IP header and this
> ambiguity does not exist. [REQUIRED for all implementations]
Is this sentence saying,
when implementing SPD, the implementor Must support *ALL* parameters
setting below for dest-IP ?
- single IP
- multicast
- a range of addresses (high and low values
- address + mask
- a wildcard address
or,
are these only candidate of dest-IP setting and whole parameter's support
being not mandatory?
Thanks in advance.
