The OSPF feature uses NSF to enable the hardware to continue forwarding
IPv4 packets using OSPF routes while a backup unit takes over stack master
responsibility. Additional NSF commands are available in OSPF and OSPFv3
command modes. For more information, see "NSF OSPF Configuration" on
page 1137 and "NSF OSPFv3 Configuration" on page 1154
