ipv6 route bfd
Enables or disables BFD on IPv6 static routes.
Syntax
ipv6 route bfd [vrf vrf-name] [interval millisec min_rx min_rx multiplier
role {active | passive}]
To disable BFD on a IPv6 static route, use the no ipv6 route bfd command.
Parameters
● vrf vrf-name — Enter the keyword VRF followed by 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. 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
Usage
Information
● This command can be used to enable or disable BFD for all the configured IPv6 static route for
specified VRF. If VRF name is not specified the command will be applicable for default VRF.

show bfd neighbors
Displays information about BFD neighbors from all interfaces using the default VRF.
Syntax
show bfd neighbors [detail]
Parameters detail — (Optional) View detailed information about BFD neighbors.
Default Not configured
Command Mode EXEC
Usage
Information
Use the show bfd neighbors command to verify that a BFD session between neighbors is up using the
default VRF instance. Use the detail parameter to view the BFD session parameters.
