Figure 32-14 shows the convergence settings when fast-convergence is enabled and Figure 32-15 shows
settings when fast-convergence is disabled. These displays appear with the
show ip ospf command.

Change OSPFv2 parameters on interfaces
In FTOS, you can modify the OSPF settings on the interfaces. Some interface parameter values must be
consistent across all interfaces to avoid routing errors. For example, you must set the same time interval for
the hello packets on all routers in the OSPF network to prevent misconfiguration of OSPF neighbors.
