Configure A Route Map For Route Tagging; Continue Clause - Dell Force10 S4810P Configuration Manual

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
only certain static routes into OSPF. According to the route map static ospf, only routes that have a
next hop of Gigabitethernet interface 0/0 and that have a metric of 255 will be redistributed into the OSPF
backbone area.
Note: When re-distributing routes using route-maps, the user must take care to create the
route-map defined in the redistribute command under the routing protocol. If no route-map is
created, then NO routes are redistributed.

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 and that tag is passed along with the
route as it passes through different routing protocols. This tag can then be used when the route leaves a
routing domain to redistribute those routes again.
In the following example, the
mode to apply a tag of 34 to all internal OSPF routes that are redistributed into RIP.
!
router rip
redistribute ospf 34 metric 1 route-map torip
!
route-map torip permit 10
match route-type
set tag
!

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 the
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 will be processed.
