66
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 by its name, a case-sensitive string of 1 to 63
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 no type is 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. This keyword is available only for VPNs.
Usage guidelines
This command redistributes a default route in a Type-5 LSA, which cannot be redistributed with the
import-route command. If the local routing table has no default route, you must provide the always
keyword for the command.
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.
Examples
# Generate a default route into the OSPF routing domain, regardless of whether the default route exists
in the local routing table.
