11.6  BFD configuration
BFD (Bidirectional Forwarding Detection) is a protocol operating over other protocols and allowing to reduce 
the problem detection time to 50 msec. BFD is two-party protocol, it requires the configuration of both routers 
(both routers generate BFD packets and respond to each other).
By default, the session is established in the following mode:
Protocol Mode
iBGP multi-hop
eBGP single-hop
eBGP multi-hop multi-hop
OSPF single-hop
Static route single-hop
To change the behavior (mode), manually override the session parameters by specifying the required mode. 
Example is given below.
