HP 6125XLG Layer 3 - Ip Routing Configuration Manual page 184

2. Configure IS-IS on the switches to make sure 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 IS-IS.
(Details not shown.)
3. Enable IS-IS NSR on Switch S.

Verifying the configuration
After Switch S establishes adjacencies with Switch A and Switch B, they begin to exchange routing
information. After network convergence, perform an active/standby switchover on Switch S. During the
switchover period, execute the display isis peer command to display the Switch S' neighborships with
Switch A and Switch B; execute the display isis route command to verify that Switch A has a route to the
loopback interface of Switch B, and Switch B has a route to the loopback interface of Switch A.
# Reoptimize process placement on Switch S to trigger an active/standby switchover.
