packets and look on them as normal broadcast or multicast packets. Connec-
tions are continually established by the RIPs if this router holds the default
route to a remote router. This can be prevented by entering the RIP port in the
filter tables.
Scaling with IP RIP
If you use several routers in a local network with IP RIP, you can represent the
routers outwardly as one large router. This procedure is also known as “scal-
ing”. As a result of the constant exchange of information between the routers,
such a router theoretically has no limits to the transmission options available
to it.
Configuration of IP- RIP function
̈ In the field 'RIP support' (or 'RIP type') the following selection is possible:
୴ 'off': IP-RIP is not used (default).
୴ 'RIP-1': RIP-1 and RIP-2 packets are received but only RIP-1 packets
are sent.
୴ 'RIP-1 compatible': RIP-1 and RIP-2 packets are received. RIP-2 pack-
ets are sent as an IP broadcast.
୴ 'RIP-2': Similar to 'RIP-1 compatible', except that all RIP packets are
sent to the IP multicast address 224.0.0.9.
̈ The entry under 'RIP-1 mask' (or 'R1 mask') can be set to the following
values:
୴ '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:
