Step 2 Enable BFD globally and configure PIM BFD in the interface view.
# Enable BFD globally on Switch B and Switch C, enable PIM BFD on the interfaces that are
connected to the network segment where the host resides, and set PIM BFD parameters. The
configuration on Switch C is similar to the configuration on Switch B and is not provided here.
[SwitchB] bfd
[SwitchB-bfd] quit
[SwitchB] interface vlanif 100
[SwitchB-Vlanif100] pim bfd enable
[SwitchB-Vlanif100] pim bfd min-tx-interval 200 min-rx-interval 200 detect-
multiplier 3
Step 3 Verify the configuration.
# Run the display pim interface verbose command, and you can view detailed information
about the interface that runs PIM. The information about the interface that runs PIM on Switch
B indicates that the DR on the network segment where the host is located is Switch C. PIM BFD
is enabled on the interface.
[SwitchB] display pim interface vlanif100 verbose
VPN-Instance: public net
Interface: Vlanif100, 10.1.1.1
# Run the display pim bfd session command to display information about the BFD session on
each switch. You can check whether the BFD session is set up on each switch.
[SwitchB] display pim
