Parameter
value: Default routing cost of external route imported by OSPF, ranging from 0 to
16,777,214. By default, its value is 1.
Description
Use the default cost command to configure the default cost for OSPF to import
external routes.
Use the undo default cost command to restore the default routing cost of external
routes to its default value.
Since OSPF can import external routing information and propagate the information to
the entire autonomous system, routing cost of external routes can influence route
selection and calculation. Therefore, it is necessary to specify the default routing cost
for the protocol to import external routes.
Example
# Specify the default routing cost for OSPF to import external routes as 10.
