Multi-Area IS-IS
If a network is a larger one, consider the use of multiple IS-IS
areas. Based on geographic locations and functions, close
routers can be divided into same area. The area division helps to
reduce the requirements for memory, so that routers in the area
only need to maintain a smaller link state database. Figure 93
show a multi-area IS-IS configuration example.

Where, R1 belongs to area 1, R2, R3 and R4 belong to area 0,
and R5 and R6 belong to area 2. On R1, route aggregation is
performed for network sections in area 1. Default routes on R6
are redistributed into IS-IS.
The detailed configuration of each router in the above figure is
as follows:
Configuration of R1:
ZXR10_R1(config)#router isis
ZXR10_R1(config-router)#area 01
ZXR10_R1(config-router)#system-id 00D0.D0C7.53E0
