• interval milliseconds - Enter the time interval for sending control packets to BFD peers, from 100 to 1000. • 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 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. The number of consecutive packets that must be received from a BFD peer is 3. The BFD role is active. Command Mode CONFIG Usage Information • Use this command to enable or disable BFD for all the configured IPv6 static routes for the specified VRF. If you do not specify a VRF name, the command is applicable for the default VRF. The no version of this command disables BFD on an IPv6 static route. Example OS10(config)# ipv6 route bfd interval 250 min_rx 250 multiplier 4 role active Supported releases 10.4.2E or later show bfd neighbors Displays information about BFD neighbors from all interfaces using the default VRF. Syntax Parameters show bfd neighbors [detail | interface] • detail - (Optional) View detailed information about BFD neighbors. • active - (Optional) View information about the active BFD neighbors whose state is up. • interface interface-type - (Optional) Enter one of the following interface types: ○ ethernet node/slot/port[:subport] - Displays Ethernet interface information. ○ port-channel id-number - Display port channel interface IDs, from 1 to 128. ○ vlan vlan-id - Displays the VLAN interface number, from 1 to 4093. Default Not configured Command Mode EXEC Usage Information Use this command to verify that a BFD session between neighbors is up using the default VRF instance. Use the detail par the BFD session parameters.
