OSPFv3 NSR configuration example

As shown in Figure 94, Switch S, Switch A, and Switch B belong to the same AS and OSPFv3 routing domain. Enable OSPFv3 NSR on Switch S to ensure correct routing when an active/standby switchover occurs on Switch S.

1. Configure IPv6 addresses for interfaces. (Details not shown.)

2. Configure OSPFv3:

   # On Switch A, enable OSPFv3, and set the router ID to 1.1.1.1.

   <SwitchA> system-view
   [SwitchA] ospfv3 1
   [SwitchA-ospfv3-1] router-id 1.1.1.1
   [SwitchA-ospfv3-1] quit
   [SwitchA] interface vlan-interface 100
   [SwitchA-Vlan-interface100] ospfv3 1 area 1
   [SwitchA-Vlan-interface100] quit
   

   # On Switch B, enable OSPFv3, and set the router ID to 2.2.2.2.

   <SwitchB> system-view
   [SwitchB] ospfv3 1
   [SwitchB-ospfv3-1] router-id 2.2.2.2
   [SwitchB-ospfv3-1] quit
   [SwitchB] interface vlan-interface 200
   [SwitchB-Vlan-interface200] ospfv3 1 area 1
   [SwitchB-Vlan-interface200] quit
   

   # On Switch S, enable OSPFv3, set the router ID to 3.3.3.3, and enable NSR.

   <SwitchS> system-view
   [SwitchS] ospfv3 1
   [SwitchS-ospfv3-1] router-id 3.3.3.3
   [SwitchS-ospfv3-1] non-stop-routing
   [SwitchS-ospfv3-1] quit
   [SwitchS] interface vlan-interface 100
   [SwitchS-Vlan-interface100] ospfv3 1 area 1
   [SwitchS-Vlan-interface100] quit
   [SwitchS] interface vlan-interface 200
   [SwitchS-Vlan-interface200] ospfv3 1 area 1
   [SwitchS-Vlan-interface200] quit
   

# Perform an active/standby switchover on Switch S, and verify that NSR can ensure continuous traffic forwarding between Switch A and Switch B. (Details not shown.)
