When the router does not receive any messages from a neighbor in
<m/dead/ seconds, it will consider the neighbor down. If both directives
<m/dead count/ and <m/dead/ are used, <m/dead/ has precendence.

BIRD detects a type of a connected network automatically, but sometimes it's
convenient to force use of a different type manually.
