Object
Set this object to 'true' to minimize the delay before
triggering a routing calculation that includes any
relevant circuit change. This means a change to the local
neighbors (including pseudonodes), or to the reachable
addresses received from the I3 stub.
There are two aspects to minimizing the delay.
- DC-ISIS overrides the setting of the
isisSysLevelMinLSPGenInt object when such a change
occurs, and usually regenerates the local LSP(s)
immediately. The only exception is when DC-ISIS is
performing restart procedures as defined in RFC3847.
This RFC specifies when DC-ISIS can update the local
LSP during a restart.
- DC-ISIS overrides all of the objects that affect the
scheduling of routing calculations, with the exception
of the isisSysCalcThrshRestartLimit object. It ensures
that a routing calculation including the updated LSPs
takes place as soon as possible. It abandons an
existing route calculation if necessary, unless more
than isisSysCalcThrshRestartLimit successive
calculations would have been interrupted.
