Description
Incremented for the following events:
• A DD is received from the neighbor with an MTU mismatch.
• The neighbor sent an ACK for an LSA not on the neighbor's
retransmit list.
• The state of the adjacency changed.
The number of LSAs on the neighbor's retransmit queue
waiting for the neighbor to acknowledge.
One of two values:
• Helping — This router is acting as a helpful neighbor to this
neighbor. A helpful neighbor does not report an adjacency
change during graceful restart, but continues to advertise the
restarting router as a FULL adjacency. A helpful neighbor
continues to forward data packets to the restarting router,
trusting that the restarting router's forwarding table is
maintained during the restart.
• Not Helping — This router is not a helpful neighbor at this
time.
