When any neighbors are added to either interface, PIM informs BFD about the newly added neighbor(s);
BFD then establishes a session with them. Use the show ip|ipv6 bfd sessions command to view BFD
sessions with all BFD neighbors, as shown below:
-> show ip bfd sessions
Legends: Neg. = Negotiated
Discr = Discriminator
Intvl = Interval (in milliseconds)
Local Interface Neighbor State Remote Neg. Rx Neg. Tx EchoRx
Discr Name Address Discr Intvl Intvl Intvl

To view a BFD session with a particular neighbor, use the show ip|ipv6 bfd sessions command followed
by the session number. For example:
-> show ip bfd sessions 1
Local discriminator = 1,
Neighbor IP Address = 101.1.1.11,
Requested Session Type = ASYNC ,
Interface IfIndex = 2,
Source UDP Port = 49153,
State = UP,
Session Operating Mode = None,
Remote discriminator = 1,
Negotiated Tx interval = 300,
Negotiated Rx interval = 300,
Echo Rx interval = 300,
Multiplier = 3,
Applications Registered: = OSPF
-> show ipv6 bfd sessions 1
Local discriminator = 1,
Neighbor IP Address = fe80::2efa:a2ff:fe13:e402,
Requested Session Type = ECHO,
