Use the
redistribute
command in OSPF, RIP, ISIS, and BGP to set some of these attributes for routes
that are redistributed into those protocols.
Route maps add to that redistribution capability by allowing you to match specific routes and set or
change more attributes when redistributing those routes.
In the following example, the
redistribute
command calls the route map
static ospf
to
redistribute only certain static routes into OSPF. According to the route map
static ospf
, only routes
that have a next hop of Tengigabitethernet interface 1/1/1 and that have a metric of 255 are redistributed
into the OSPF backbone area.
NOTE: When re-distributing routes using route-maps, you must create the route-map defined in
the
redistribute
command under the routing protocol. If you do not create a route-map, NO
routes are redistributed.
Example of Calling a Route Map to Redistribute Specified Routes
router ospf 34
default-information originate metric-type 1
redistribute static metric 20 metric-type 2 tag 0 route-map staticospf
!
route-map staticospf permit 10
match interface TenGigabitEthernet 1/1/1
match metric 255
set level backbone
Configure a Route Map for Route Tagging
One method for identifying routes from different routing protocols is to assign a tag to routes from that
protocol.
As the route enters a different routing domain, it is tagged. The tag is passed along with the route as it
passes through different routing protocols. You can use this tag when the route leaves a routing domain
to redistribute those routes again. In the following example, the
redistribute ospf
command with a
route map is used in ROUTER RIP mode to apply a tag of 34 to all internal OSPF routes that are
redistributed into RIP.
Example of the
redistribute
Command Using a Route Tag
!
router rip
redistribute ospf 34 metric 1 route-map torip
!
route-map torip permit 10
match route-type internal
set tag 34
!
Continue Clause
Normally, when a match is found, set clauses are executed, and the packet is then forwarded; no more
route-map modules are processed.
If you configure the
continue
command at the end of a module, the next module (or a specified
module) is processed even after a match is found. The following example shows a continue clause at the
end of a route-map module. In this example, if a match is found in the route-map “test” module 10,
module 30 is processed.
