OSPF NSR configuration example
Network requirements
As shown in Figure 32, Switch S, Switch A, and Switch B belong to the same OSPF routing domain.
Enable OSPF NSR on Switch S to ensure correct routing when an active/standby switchover occurs
on Switch S.
Figure 32 Network diagram
Configuration procedure
1. Configure IP addresses and subnet masks for interfaces on the switches. (Details not shown.)
2. Configure OSPF on the switches to ensure the following: (Details not shown.)
 Switch S, Switch A, and Switch B can communicate with each other at Layer 3.
 Dynamic route update can be implemented among them with OSPF.
3. Enable OSPF NSR on Switch S.
