Hi,
The request was for a combined type that contains both an ip address
*and* a prefix length in one value. Hence the name
"ip-address-and-prefix-length" :)
Ok - I understand now.
I know that this type is convenient, esp. if you use it for manual
input, but I wonder if it really is good practice to squeeze two
values into one.
Agreed. It seems a prefix with a prefix length of 32 for IPv4 or 128 for IPv6
would allow specification.
No, it does not. You must be referring to some other use case. I want to
configure the IP address and prefix-length on an interface. The
prefix-length naturally needs to align with the prefix-length / subnet
mask used on the network to which the interface is connected. If it is a
/24 network then the prefix-length needs to be 24. I can't just say it's
a /32 so I can enter this information - the router wouldn't understand
what is then connected to that network / interface and wouldn't be able
to route packets correctly.
At the same time, I need to specify the exact IP address to be used by
this device on the interface, so I need to have bits set to the right of
the mask, thus I can't use current ip-prefix type.
The convenience is primarily for mapping to CLI.
Heh, I don't understand what it has to do with CLI but since you're the
second person mentioning there must be some connection I don't see.
Kind regards,
Kristian.
