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.
