Enable BFD Sessions for a BGP Neighbor

Access global configuration mode.
```
device# configure terminal
```
Access BGP configuration mode.
```
device(config)# router bgp
```
To enable BFD sessions for a specified neighbor:
```
device(config-bgp-router)# neighbor 10.10.1.1 bfd
```
To specify the transmit time, the receive time, and the number of consecutive control packets that must be missed before the connection to a peer is considered non-operational:
```
device(config-bgp-router)# neighbor 10.10.1.1 bfd interval 120 min-rx 140 multiplier 10
```
For neighbor 10.10.1.1, this example specifies a transmit interval of 120 ms, the min-rx keyword followed by a receive interval of 140 ms, and the multiplier value of 10, which indicates that 10 consecutive packets must be missed before the connection to the peer is considered non-operational.
To specify the interval (in seconds) after which BGP routes are withdrawn after a BFD session is declared down:
```
device(config-bgp-router)# neighbor 10.10.1.1 bfd holdover-interval 12
```
For neighbor 10.10.1.1, this example specifies a holdover interval of 12 seconds.
