division is helpful to decrease the demand for memory, and the routers in each area only
need to maintain a smaller link state database.

S4 in Area 2. On S1, perform route aggregation for the network segments in Area 1. The
direct routes are redistributed to the IS-IS on R4.

Configuration Thought
1. Enable the IPv6 protocol on the interfaces, configure IPv6 addresses for these
interfaces, configure loopback interfaces, enable IPv6 on the loopback interfaces,
and configure IPv6 addresses for the loopback interfaces.
2. Configure the IS-ISv6 protocol and ensure that the system-ids of the routers are not
the same. Establish L2 neighbors between S2 and S1/S3, and establish L1 neighbors
between S3 and S4. Here, the multi-topology environment is taken as an example.
3. Enable the IS-ISv6 protocol on the interfaces.
4. Enable route aggregation on S1.
5. Redistribute the direct route on S4.
6. Check and verify the configuration results: The routers can correctly establish
neighbors and correctly compute the IPv6 topology, and the interface addresses of
the routers can be successfully pinged from each other
Configuration Commands
