Statistics	Description
Nbr Change Stats:
hello	The sum total of all Hello packets received from neighbors on all OSPF
	areas and interfaces.
Start	The sum total number of neighbors in this state (that is, an indication that
	Hello packets should now be sent to the neighbor at intervals of Hel-
	loInterval seconds.) across all OSPF areas and interfaces.
n2way	The sum total number of bidirectional communication establishment
	between this router and other neighboring routers.
adjoint ok	The sum total number of decisions to be made (again) as to whether an
	adjacency should be established/maintained with the neighbor across all
	OSPF areas and interfaces.
negotiation done	The sum total number of neighbors in this state wherein the Master/slave
	relationship has been negotiated, and sequence numbers have been
	exchanged, across all OSPF areas and interfaces.
exchange done	The sum total number of neighbors in this state (that is, in an adjacency's
	final state) having transmitted a full sequence of Database Description
	packets, across all OSPF areas and interfaces.
bad requests	The sum total number of Link State Requests which have been received
	for a link state advertisement not contained in the database across all
	interfaces and OSPF areas.
bad sequence	The sum total number of Database Description packets which have been
	received that either:
	a) Has an unexpected DD sequence number
	b) Unexpectedly has the init bit set
	c) Has an options field differing from the last Options field
	received in a Database Description packet.
	Any of these conditions indicate that some error has occurred during
	adjacency establishment for all OSPF areas and interfaces.
loading done	The sum total number of link state updates received for all out-of-date
	portions of the database across all OSPF areas and interfaces.
n1way	The sum total number of Hello packets received from neighbors, in which
	this router is not mentioned across all OSPF interfaces and areas.
rst_ad	The sum total number of times the Neighbor adjacency has been reset
	across all OPSF areas and interfaces.
down	The total number of Neighboring routers down (that is, in the initial
	state of a neighbor conversation.) across all OSPF areas and interfaces.
