notes: EIGRP BFD

Bidirectional Failure Detection

- its not a feature specific for EIGRP
- rapid detection of failures in forwarding path
- configured on interface and under process.
- only detects the failure, protocol responsible for reacting.
- one session for multiple protocols between peers.
I.E OSPF AND EIGRP only one session.
