Default Level
2: System level
Parameters
always: Generates a default route in an ASE LSA into the OSPF routing domain regardless of whether
the default route exists in the routing table. Without this keyword, the command can distribute a default
route in a Type-5 LSA into the OSPF routing domain only when the default route exists in the routing
table.
cost cost: Specifies a cost for the default route, in the range 0 to 16777214. The default is 1.
type type: Specifies a type for the ASE LSA: 1 or 2. The default is 2.
route-policy route-policy-name: Specifies a route policy name, a string of 1 to 19 characters.
Description
Use the default-route-advertise command to generate a default route into the OSPF routing domain.
Use the undo default-route-advertise command to disable OSPF from redistributing a default route.
By default, no default route is redistributed.
Using the import-route command cannot redistribute a default route. To do so, you need to use the
default-route-advertise command. If no default route exists in the router's routing table, use the
default-route-advertise always command to generate a default route in a Type-5 LSA.
You can reference a routing policy to set the cost and type of the default route:
The router advertises the default route only when it passes the routing policy.
The default route passing the routing policy uses the cost set by the apply cost clause, and the
type set by the apply cost-type clause in the routing policy.
The default route cost's priority from high to low is: the cost set by the apply cost clause in the
routing policy, the one set by the default-route-advertise command and the one set by the default
cost command.
The default route type's priority from high to low is: the type set by the apply cost-type clause in
the routing policy, and the one set by the default-route-advertise command.
If the always keyword is included, the default route is advertised regardless of whether it passes
the routing policy and uses the cost and type specified by the apply cost, apply cost-type clauses
in the first node of the routing policy.
