cspf tie-break
Use this command to set the tie-break method for an OSPFv2 instance. This selects a link (during route computation) when more than one candidate link satisfies all the route constraints and the associated cost and hop limit link attributes are equal.
Use the no parameter with this command to unset tie-break method.
Command Syntax
cspf tie-break (random|least-fill|most-fill)
no cspf tie-break
Parameters
random
Pick any path at random. This method places an equal number of LSPs on each link without taking into account the available bandwidth ratio. This is the default tie-break method.
least-fill
Pick the path with the largest minimum available bandwidth ratio. This method equalizes the reservation on each link.
most-fill
Pick the path with the smallest minimum available bandwidth ratio. This method uses one link until it is completely full and then uses the next link.
Default
By default, the tie-break method is set to random.
Command Mode
Configure mode
Applicability
This command was introduced before OcNOS version 1.3.
