Set protocol MRTdump flags. MRTdump is a standard binary
|

format for logging information from routing protocols and
|

daemons. These flags control what kind of information is
|
||||
logged from the protocol to the MRTdump file (which must be
|
||||
specified by global <cf/mrtdump/ option, see the previous
|
||||
section). Although these flags are similar to flags of
|
||||
<cf/debug/ option, their meaning is different and
|
||||
protocol-specific. For BGP protocol, <cf/states/ logs BGP
|

state changes and <cf/messages/ logs received BGP messages.
