Configuration procedure 
1. Configure IP addresses of the interfaces  on each switch and configure IS-IS:  
Follow  Figure 66  to c
 onfigure the IP address and subnet mask of each interface. (Details not 
shown.) 
Configure IS-IS on the switches, ensuring that Sw itch A, Switch B and Switch C can communicate 
with each other at layer 3 and dynamic route update can be implemented among them with IS-IS. 
(Details not shown.)

IS-IS authentication configuration example 
Network requirements 
As shown in Figure 69, S witch A, Switch B, Switch C and Switch D reside in the same IS-IS routing 
domain. 
Switch A, Switch B, and Switch C belong to  Area 10, and Switch D belongs to Area 20. 
Configure relationship authentication between neighbors. Configure area authentication in Area 10 to 
prevent untrusted routes from entering into the area. Configure routing domain authentication on Switch 
C and Switch D to prevent...
