Configuring OSPF NSR
Network requirements
As shown in Figure 46 , Switch S, Switch A, and Switch B belong to the same OSPF routing domain.
Switch S is a distributed device. Enable OSPF NSR on Switch S to ensure correct routing when an
active/standby switchover occurs on Switch S.
Figure 46 Network diagram for OSPF NSR configuration
Configuration procedure
1. Configure IP addresses for the interfaces on each switch and configure OSPF.
Follow Figure 46 to configure the IP address and subnet mask of each interface on the switches. (Details
