Configuration Roadmap
The configuration roadmap is as follows:
1. Create the ID of the VLAN to which each interface belongs.
2. Assign an IP address to each VLANIF interface.
3. Configure basic IS-IS functions on Switch-B and Switch-C.
4. Configure OSPF on Switch-A and Switch-B and import IS-IS routes.
5. Configure a routing policy on Switch-B and apply the routing policy when OSPF imports
IS-IS routes, and verify the routes.
Data Preparation
To complete the configuration, you need the following data:
l The IS-IS level of Switch-C is Level-2. The system ID is ID 0000.0000.0001. The IS-IS
level of Switch-B is Level-2. The system ID is ID 0000.0000.0002. The area number of
Switch-B and Switch-C is 10.
l Switch-A and Switch-B are located in Area 0, that is, the backbone area.
l Configure the names of the filtering list and IP prefix list. The cost of the route 172.17.1.0/24
is 100 and the tag of the route 172.17.2.0/24 is 20.
Configuration Procedure
1. Create a VLAN to which each interface belongs.
The configuration details are not mentioned here.
