Configuration procedure
1. Configure the IP addresses and subnet masks for interfaces on the switches. (Details not
shown.)
2. Configure IS-IS on the switches to make sure Switch S, Switch A, and Switch B can
communicate with each other at Layer 3 and dynamic route update can be implemented among
them with IS-IS. (Details not shown.)
3. Enable IS-IS NSR on Switch S.
