Supported releases 10.4.2E or later ipv6 ospf bfd all-neighbors Enables and configures the default BFD parameters for all OSPFv3 neighbors in this interface. Syntax ipv6 ospf bfd all-neighbors [disable|[interval millisec min_rx min_rx multiplier role {active | passive}]] To disable default BFD parameters for all OSPFv3 neighbors using the no ipv6 ospf bfd all-neighbors. Parameters • disable - Disables the BFD session on an interface alone. • interval milliseconds - Enter the time interval for sending control packets to BFD peers, from 100 to 1000. You cannot configure a value that is less than 100 milliseconds. • min_rx milliseconds - Enter the maximum waiting time for receiving control packets from BFD peers, from 100 to 1000. Dell EMC recommends using more than 100 milliseconds. • multiplier number - Enter the maximum number of consecutive packets that must not be received from a BFD peer before the session state changes to Down, from 3 to 50. • role {active | passive} - Enter active if the router initiates BFD sessions. Both BFD peers can be active at the same time. Enter passive if the router does not initiate BFD sessions, and only responds to a request from an active BFD to initialize a session. Default The time interval for sending control packets to BFD peers is 200 milliseconds. The maximum waiting time for receiving control packets from BFD peers is 200 milliseconds. The number of consecutive packets that must be received from a BFD peer is 3. The BFD role is active Command Mode CONFIG-INTERFACE Usage Information • This command can be used to enable or disable BFD for an interface associated with OSPFv3. Interface level BFD configuration takes precedent over the OSPF global level BFD configuration. If there is no BFD configuration present at the interface level global OSPF BFD configuration will be inherited. All types of interfaces are supported. Example (conf-if-eth1/1/1)#ipv6 ospf bfd all-neighbors Supported releases 10.4.2E or later ip route bfd Enables or disables BFD on static routes. Syntax Parameters ip route bfd [vrf vrf-name] [interval interval min_rx wait-time multiplier number role {active | passive}] • vrf vrf-name - Enter vrf and then the name of the VRF to configure static route in that VRF. • interval milliseconds - Enter the time interval for sending control packets to BFD peers; from 100 to 1000. Dell EMC recommends using more than 100 milliseconds. • min_rx milliseconds - Enter the minimum waiting time for receiving control packets from BFD peers, from 100 to 1000. Dell EMC recommends using more than 100 milliseconds. • multiplier number - Enter the maximum number of consecutive packets that must not be received from a BFD peer before the session state changes to Down; from 3 to 50. • role {active | passive} - Enter active if the router initiates BFD sessions. Both BFD peers can be active simultaneously. Enter passive if the router does not initiate BFD sessions, and only responds to a request from an active BFD to initialize a session. Default The time interval for sending control packets to BFD peers is 200 milliseconds. The maximum waiting time for receiving control packets from BFD peers is 200 milliseconds. Layer 3 509
