OSPFv3 NSSA area configuration example
Network requirements
As shown in Figure 89:
• Configure OSPFv3 on all switches and split the AS into three areas.
• Configure Switch B and Switch C as ABRs to forward routing information between areas.
• Configure Area 1 as an NSSA area and configure Switch A as an ASBR to redistribute static
routes into the AS.

Configuration procedure
1. Configure IPv6 addresses for interfaces. (Details not shown.)
2. Configure basic OSPFv3 (see "OSPFv3 stub area configuration example").
