Configure OSPF on the switches, ensuring that Switch S, Switch A, and Switch B can communicate with
each other at Layer 3 and dynamic route update can be implemented among them with OSPF. (Details
not shown)
2. Configure OSPF NSR.
# Enable OSPF NSR on Switch S.

[SwitchS] ospf non-stop-routing
3. Verify the configuration.
After Switch S establishes neighbor relationships with Switch A and Switch B, they start to exchange
routing information. After network convergence, perform an active/standby switchover on Switch S.
During the switchover period, use the display ospf peer command to check the neighbor relationship
between Switch A and Switch S and between Switch B and Switch S; use the display ospf routing
command to check if there are routes from Switch A to the loopback interface on Switch B and from
Switch B to the loopback interface on Switch A.
# When an active/standby switchover occurs on Switch S, display OSPF neighbors and routes on Switch
A.
