Configuring OSPF

Dynamic OSPF Activation and Configuration

OSPF is automatically activated when you enable it. The protocol does not require a software reload.

Without ever having to reset the switch, you can change and save all the OSPF configuration options, including the following:

all OSPF interface-related parameters (for example: area, hello timer, router dead time cost, priority, re-transmission time, transit delay)

all area parameters

all area range parameters

all virtual-link parameters

all global parameters

creation and deletion of an area, interface or virtual link

changes to address ranges

changes to global values for redistribution

addition of new virtual links

The only configuration change that requires you to disable and then re-enable OSPF operation is reconfiguring the Router ID.
