ype| nssa-external type] [[tag tag] [route-
map route-map-name] [subnets]
Set route redistribution.
Protocol (protocol type): bgp,
connected, isis, rip, static
DES-7200(config-router)# default-metric
metric
Set the default metric for all
redistributed routes.
Route redistribution may easily cause loops, so you must be very careful in using
them.
Note
When the route redistribution is configured in the OSPF routing process, the
metric of 20 is allocated to the redistributed routes with the type of Type-2 by
default. This type belongs to the least credible route of the OSPF.
1.3.2 Configuring Default Route Distribution
To advertise the default route, it is necessary for routing protocol to introduce the
default route to the process, or enforce generating a default route.
To distribute the default route, execute the following commands in the routing
process configuration mode:
Command Function
DES-7200(config-router)#
default-information originate [always]
[metric metric] [metric-type type]
[route-map map-name]
Introduce the default route to the
routing protocol process and
advertise the route default.
always(optional): a default route
is always introduced to the
process no matter whether the
default route exists in the local
routing table or not.
metric(optional): set the metric
value for the introduced default
route.
metric-type(optional): set the
default route type.
route-map(optional): filter and
set the default route.
DES-7200(config-router)# no
default-information originate [always]
[metric metric] [metric-type type]
[route-map map-name]
Cancel the introduction of the
default route to the routing
protocol process and the route
default advertisement.
