Conﬁguring a multi-area complex

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.
