LABEL DESCRIPTION
Active OSPF for IPv4 is disabled by default. Enable the switch button to enable it.
Router ID Router ID uniquely identifies the Switch in an OSPF. Enter a unique ID (that uses the format of an
IP address in dotted decimal notation) for the Switch.
Distance Enter a number from 10 to 255 to specify the administrative distance that is assigned to routes
learned by OSPF.
The lower the administrative distance value is, the more preferable the routing protocol is.
Note: You cannot set two routing protocols to have the same administrative
distance.
Default-
information
Originate Enable the switch button in the Active field to advertise a default route in your OSPF network if
there is one in the routing table. When no matching route is found in the routing table, the
default route will be used to forward traffic.
Always Select the check box to have the Switch advertise a default route to neighboring OSPF routers
even if the Switch does not have one in its routing table.
Metric Enter a route cost (between 0 and 16777215) for the default route.
