Conﬁguring a multi-area complex

IP routing conﬁguration examples 153

The multi-area complex conﬁguration example described in this section uses ﬁve Nortel Ethernet Routing Switch 5500 Series devices (R1 to R5) in a multi-area conﬁguration.

Many of the concepts and topology descriptions that are used in this example conﬁguration are described in the previous sections of this chapter. The concepts shown in those examples are combined in this example conﬁguration to show a real world topology example with command descriptions.

Multi-area complex example

For this conﬁguration example, the Nortel Ethernet Routing Switch 5500 Series devices R1 through R5 are conﬁgured as follows:

•R1 is an OSPF ABR that is associated with OSPF Area 0 and 3.

•R2 is an OSPF Stub ABR for OSPF Area 2 and ABR to OSPF Area 3.

•R3 is an OSPF ASBR and is conﬁgured to distribute OSPF to RIP and RIP to OSPF.
