Peer Groups in Areas
Multiple peer groups can exist within an area. Peer groups within an area are connected to
each other by border links as shown in Figure 6.3.

Area IDs
Each area has an area ID which is unique only within a domain. The area ID is only useful at
the border of the area. Since area IDs are included in some of the routing packets distributed
throughout a domain, all switches belonging to the same area must be configured with the
same area ID. It is especially important for the nodes in split switches and gateway switches to
be configured with the correct area ID.
