IS-IS NSR configuration example

Network requirements
Switch S, Switch A, and Switch B belong to the same IS-IS routing domain as illustrated in
Switch S is an IRF fabric, which is connected to Switch A and Switch B over aggregated links. Enable IS-IS
NSR on Switch S to ensure correct routing when a master/slave switchover occurs on Switch S.
Figure 67 Network diagram for IS-IS NSR configuration
Configuration procedure
Configure IP addresses for the interfaces on each switch and configure IS-IS.
1.
Follow Figure 67
not shown)
Configure IS-IS 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 IS-IS. (Details not
shown)
Configure IS-IS NSR.
2.
# Enable IS-IS NSR on Switch S.
<SwitchS> system-view
[SwitchS] isis 1
[SwitchS-isis-1] non-stop-routing
[SwitchS-isis-1] non-stop-routing interval 30
[SwitchS-isis-1] return
Verify the configuration.
3.
After Switch S establishes neighbor relationships with Switch A and Switch B, they start to exchange
routing information. After network convergence, perform a master/slave switchover on Switch S. During
the switchover period, use the display isis peer command to check the neighbor relationship between
Switch A and Switch S and between Switch B and Switch S; use the display isis route command to check
to configure the IP address and subnet mask of each interface on the switches. (Details
