HP Comware 5 Debug Manual Vol 3

Field
Description
state (event)
Neighbor state state and triggering event event.
Current neighbor state:
• Down—The neighbor is down.
• Attempt—A further attempt is made to contact the neighbor after receiving nothing
from it.
• Init—The hello packets sent by the neighbor were received but 2-way communication
is not established with the neighbor.
• 2-Way—2-way communication is established.
• ExStart—The master/subordinate negotiation is performed.
• Exchange—DD packets are exchanged.
• Loading—LSR packets are sent to the neighbor.
• Full—An adjacency is established.
Triggering event:
• HelloReceived—A hello packet is received from the neighbor.
• Start—Hello packets will be sent to the neighbor at an interval of HelloInterval. This
event is only related to a neighbor on an NBMA network.
• 2-WayReceived—2-way communication is established between the two neighboring
routers.
• NegotiationDone—The master/subordinate negotiation is completed and DD
sequence numbers are exchanged.
• ExchangeDone—The two routers have exchanged DD packets successfully and know
which LSAs of the neighbor are missing from their LSDBs.
• BadLSReq—T
he received LSR contains LSAs that cannot be found in the local LSDB.
• LoadingDone—The LSR list is empty after the database exchange is complete.
• AdjOK—Indicates whether an adjacency needs to be established or maintained with
the neighbor.
• SeqNumberMismatch—An error has occurred when an adjacency is being
established.
• 1-WayReceived—The hello packet received from the neighbor does not contain the
local router.
• KillNbr—It is impossible to communicate with the neighbor and therefore the
neighbor is forced to enter the Down state.
• InactivityTimer—No hello packet has been received from the neighbor recently and
therefore the neighbor dead timer is started.
• LLDown—The neighbor is unreachable and therefore is forced to enter the Down
state.
nfsm_ignore called The received event is not processed.
