Default command level
2: System level
Parameters
always: Generates a default route in a Type-5 LSA into the OSPF routing domain regardless of whether
there is a default route in the routing table. If this keyword is not specified, the router generates a default
route in a Type-5 LSA into the OSPF routing domain only when an active default route that does not
belong to the current OSPF process exists in the IP routing table.
permit-calculate-other: Calculates default routes from other routers with this keyword specified or does
not calculate default routes from other routers without this keyword specified when the router generates
a default route in a Type-5 LSA into the OSPF routing domain. If the router generates no default route in
a Type-5 LSA into the OSPF routing domain, the router calculates default routes from other routers
regardless of whether this keyword is specified.
cost cost: Specifies a cost for the default route, in the range of 0 to 16777214. If no cost is specified, the
default cost specified by the default cost command applies.
route-policy route-policy-name: Specifies a routing policy name, a string of 1 to 63 case-sensitive
characters. When a default route exists in the routing table and the specified routing policy is matched,
the command distributes a default route in a Type-5 LSA into the OSPF routing domain, and the routing
policy modifies some values in the Type-5 LSA. If the always keyword is specified at the same time, the
command can distribute a default route in a Type-5 LSA into the OSPF routing domain when the specified
routing policy is matched, regardless of whether a default route exists in the routing table, and the routing
policy modifies some values in the Type-5 LSA.
type type: Specifies a type for the Type-5 LSA: 1 or 2. If type is not specified, the default type for the
Type-5 LSA specified by the default type command applies.
summary: Advertises the specified default route in a Type-3 LSA.
Usage guidelines
The default-route-advertise summary cost command is applicable only to VPNs. It enables a PE router
to redistribute a default external route in a Type-3 LSA to CE routers.
This command redistributes a default AS-external route which cannot be redistributed with the
import-route command.
