Example for Configuring Basic OSPFv3 Functions
Networking Requirements
As shown in Figure 6-12, all switches run OSPFv3. The entire autonomous system is divided into three areas. SwitchB and SwitchC serve as ABRs to forward the inter-area routes.
After the configuration, each router should learn the routes from the AS to all network segments.
Configuration Roadmap
The configuration roadmap is as follows:
Enable basic OSPFv3 functions on each switch.
Check the routing list and LSDB.
Procedure
- Assign an IPv6 address to each interface. The detailed configuration is not provided here.
- Configure basic OSPFv3 functions.
