Multinet

Multinet, a feature of the Internet Protocol (IP), allows you to support many IP

networks over one SMDS line by allowing many hosts on a single logical IP

subnetwork. A multinet network is economical because you do not have to

purchase as many SMDS group addresses from your SMDS provider as you might

with other conﬁgurations.

Multinet conﬁgurations enable you to conﬁgure one SMDS individual address and

one SMDS group address for a single SNI and then associate many logical IP

subnetworks with these single SMDS addresses. A logical IP subnetwork is a host

that is directly connected to the SMDS network.

A second variation of a multinet conﬁguration allows you to have multiple SMDS

individual addresses along with a single SMDS group address by conﬁguring an

individual address per IP host address for the same group address. For information

about IP, refer to Conﬁguring IP Services.

igure 2-4 shows the two types of multinet conﬁgurations.

Figure 2-4. SMDS and IP Addresses for a Multinet Conﬁguration

Figure 2-5 on page 2-6 shows a sample multinet conﬁguration, where several IP

networks are using one SNI. Each side of the network shows a different use of

group and individual addresses for connecting to the IP networks. A multinet

conﬁguration allows for efﬁcient network addressing and a cost-effective method

of implementing SMDS.
