111DescriptionUse the ospf bfd enable command to enable BFD for link failure detection on an OSPF interface.Use the undo ospf bfd enable command to disable BFD on an OSPF interface.By default, an OSPF interface is not enabled with BFD.Examples# Enable OSPF and BFD on VLAN-interface 11. system-view[Sysname] ospf[Sysname-ospf-1] area 0[Sysname-ospf-1-area-0.0.0.0] network 192.168.0.0 0.0.255.255[Sysname] interface vlan-interface 11[Sysname-Vlan-interface11] ospf bfd enableospf costSyntaxospf cost valueundo ospf costViewInterface viewDefault level2: System levelParametersvalue: OSPF cost, in the range 0 to 65535 for a loopback interface and 1 to 65535 for other interfaces.DescriptionUse the ospf cost command to set an OSPF cost for the interface.Use the undo ospf cost command to restore the default.By default, the OSPF cost for a loopback interface is 0, and an OSPF interface calculates its cost with theformula: interface default OSPF cost=100 Mbps/interface bandwidth(Mbps). Default OSPF costs ofsome interfaces are:• 1785 for the 56 kbps serial interface• 1562 for the 64 kbps serial interface• 48 for the E1 (2.048 Mbps) interface• 1 for the Ethernet (100 Mbps) interfaceYou can use the ospf cost command to set an OSPF cost for an interface manually.NOTE:This configuration is not supported on null interfaces.Examples# Set the OSPF cost for the interface to 65.
