When a port isassigned to an area, all corresponding subnets on that port are automatically included in theassignment.• For NetIron MLX-32 or XMR 32000 systems running application image version 03.6.00 orlater, configured for OSPF graceful restart, and intended for use in switchover or hitlessupgrades, the OSPF dead interval must be changed to 60 seconds on OSPF interfaces. Thisensures that the graceful restart process succeeds without a timeout. For instructions onchanging the OSPF dead interval, refer to the Brocade MLX Series and NetIron FamilyConfiguration Guide.• If a Brocade NetIron XMR and Brocade MLX series router is to function as a graceful restartrouter, a secondary management module must be installed. If the router functions as agraceful restart helper router only, a second management module is not necessary.152 Brocade MLX Series and Brocade NetIron XMR Diagnostic Guide53-1002426-02
