MonitoringState(

'This state designates that bi-directional communication has been established '
'between two routers. Bi-directional means that each router has seen the other\'s '
'hello packet. This state is attained when the router receiving the hello packet '
'sees its own Router ID within the received hello packet\'s neighbor field. At '
'this state, a router decides whether to become adjacent with this neighbor. On '
'broadcast media and non-broadcast multiaccess networks, a router becomes full '
'only with the designated router (DR) and the backup designated router (BDR); it '
'stays in the 2-way state with all other neighbors. On Point-to-point and '
'Point-to-multipoint networks, a router becomes full with all connected routers. '
'At the end of this stage, the DR and BDR for broadcast and non-broadcast '
'multiacess networks are elected. For more information on the DR election process, '

'the routers and their DR and BDR establish a master-slave relationship and '
'choose the initial sequence number for adjacency formation. The router with '
'the higher router ID becomes the master and starts the exchange, and as such, '
'is the only router that can increment the sequence number. Note that one would '
'logically conclude that the DR/BDR with the highest router ID will become the '
'master during this process of master-slave relation. Remember that the DR/BDR '
'election might be purely by virtue of a higher priority configured on the '
'router instead of highest router ID. Thus, it is possible that a DR plays the '
'role of slave. And also note that master/slave election is on a per-neighbor '

'sequence number which can be incremented only by master which is explicitly '
'acknowledged by slave. Routers also send link-state request packets and '
'link-state update packets (which contain the entire LSA) in this state. The '
'contents of the DBD received are compared to the information contained in the '
'routers link-state database to check if new or more current link-state '

'information provided by the DBDs, routers send link-state request packets. The '
'neighbor then provides the requested link-state information in link-state update '
'packets. During the adjacency, if a router receives an outdated or missing LSA, '
'it requests that LSA by sending a link-state request packet. All link-state '
'update packets are acknowledged. Default monitoring state is "WARN"'),
