On a multi-core device:
# Enable BFD driver debugging on a BFD-capable device. The output in this example was created when
the following conditions exist:
•
The IP address of GigabitEthernet 1/2 is 12.1.1.61.
•
The IP address of the peer interface connected to GigabitEthernet 1/2 is 12.1.1. 8 8 .
•
The device has established OSPF neighboring relationship with the peer device.
•
The peer device has BFD enabled on its OSPF interface.
