Are the nodes marked as obstacles (DiagramNode.Obstacle = true)?

Yes. Node level obstacle property set to TRUE.

And to route all links, i am calling below piece of code:
this.diagram.LinkRouter.RouteLinks(links);


thanks,
Chiru

Please attach the diagram xml file. Are you using the default LinkRouter and routing options?

i have set the following properties for diagram.
this.diagram.RoutingOptions.Anchoring = Anchoring.Reassign;
this.diagram.RoutingOptions.DontOptimizeLongRoutes = false;
this.diagram.LinkCrossings = MindFusion.Diagramming.Silverlight.LinkCrossings.Arcs;
this.diagram.LinkStyle = LinkStyle.Cascading;
this.diagram.LinkSegments = 2;
this.diagram.DynamicLinks = true;
this.diagram.RouteLinks = true;
this.diagram.RoundedLinks = true;
this.diagram.CrossingRadius = 4.0;
this.diagram.RoundedLinksRadius = 4.0;
this.diagram.RoutingOptions.EndOrientation = MindFusion.Diagramming.Silverlight.Orientation.Auto;

this.diagram.LinkRouter = new GridRouter();

It seems the default grid size is too coarse for your diagram since the nodes are small and/or close to each other. Try setting a smaller grid size, e.g. this worked for me:

diagram.RoutingOptions.GridSize = 3;
diagram.RoutingOptions.NodeVicinityCost = 10;

Or use the default QuickRouter - it does not depend on the distance between nodes.

I hope that helps,
Stoyan
