'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 '

'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 '

'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 '
