When fast-convergence is disabled, origination and arrival LSA parameters are set to 5 seconds and 1 second, respectively. Setting the convergence parameter (1-4) indicates the actual convergence level. Each convergence setting adjusts the LSA parameters to zero, but the fast-convergence parameter setting allows for even finer tuning of the convergence speed. The higher the number, the faster the convergence. Use the following command in the ROUTER OSPF mode to enable or disable fast-convergence. Command Syntax Command Mode Usage fast-convergence {number} CONFIG-ROUTEROSPF-id Enable OSPF fast-convergence and specify the convergence level. Parameter: 1-4 The higher the number, the faster the convergence. When disabled, the parameter is set at 0 (Figure 29-15). Note: A higher convergence level can result in occasional loss of OSPF adjacency. Generally, convergence level 1 meets most convergence requirements. Higher convergence levels should only be selected following consultation with Dell Force10 technical support. 642 | Open Shortest Path First (OSPFv2 and OSPFv3)
