hjPnniAllowLGNPathLoops OBJECT-TYPE
SYNTAX TruthValue
ACCESS read-write
STATUS mandatory
DESCRIPTION
"Modifies the Dijkstra (path-calculation) algorithm in
this switch system to allow or disallow loops of
paths when computing paths through Logical Group Nodes.
When loops are disallowed (this parameter set to false),
no path will be considered which enters the same Logical
Group Node twice. This considerably lessens the time
needed to compute the paths in complicated networks.
However, under some crankback situations, this might
fail to find a viable path to the desired nodal destination.
Note that loops between lowest-level nodes (nodes within
the local node's lowest-level peer group members) are
always disallowed, regardless of the setting of this
parameter."
