[RouterA] slave auto-update config
Step 4 Enable OSPF GR on Router A, Router B, and Router D.
# Configure Router A. The configurations of Router B and Router D are the same as that of
Router A, and are not mentioned here.
[RouterA] ospf 1
[RouterA-ospf-1] opaque-capability enable
[RouterA-ospf-1] graceful-restart
Step 5 Verify the configuration.
# Run the display ospf graceful-restart command on Router A, Router B, and Router D to
check the OSPF GR status. Take the display of Router A as an example. You can find that the
value of Graceful-restart capability is enabled. This indicates that OSPF GR is enabled on Router
A.

# In the user view, run the reset ospf process graceful-restart command on Router A to restart
OSPF process 1. Run the display ospf peer command on Router D to check the OSPF neighbor
relationship between Router D and Router A. If the status of the OSPF neighbor relationship is
Full, it indicates that the relationship is not interrupted when Router A restarts the OSPF process
through GR.

# Perform the active/standby switchover on Router A. During the switchover, Router C can ping
through Router D, which indicates that service forwarding is not interrupted.Run the display
ospf peer command on Router D and Router B to check the OSPF neighbor relationship with
Router A. The statuses of the OSPF neighbor relationship are displayed as Full.
