R1-mask
If RIP-1 is set, this option allows you to influence the management of network masks. Therefore, these settings are required only for subnetting under RIP-1. The different settings have the following meaning:
|
Class (default): The network mask used in the RIP packet is derived directly from the IP address class, i.e. the following network masks are used for the network classes:
|
|
Class A: 255.0.0.0
|
|
Class B: 255.255.0.0
|
|
Class C: 255.255.255.0
|
|
Address: The network mask is derived from the first bit that is set in the IP address entered. This and all high-order bits within the network mask are set. Thus, for example, the address 127.128.128.64 yields the IP network mask 255.255.255.192.
|
|
Cl+Addr: The network mask is formed from the IP address class and a part attached after the address procedure. Thus, the above-mentioned address and the network mask 255.255.0.0 yield the IP network mask 255.128.0.0.
