To congure redistribution, perform the following tasks.
1. Congure redistribution lters (optional). You can congure lters to permit or deny redistribution for a route based on its origin
(OSPF, BGP4, and so on), the destination network address, and the route’s metric. You also can congure a lter to set the
metric based on these criteria.
2. Change the default redistribution metric (optional). The Brocade device assigns a RIP metric of 1 to each redistributed route by
default. You can change the default metric to a value up to 15.
3. Enable redistribution.
NOTE
Do not enable redistribution until you congure the other redistribution
parameters.
Conguring redistribution lters
RIP redistribution lters apply to all interfaces. Use route maps to dene how you want to deny or permit redistribution.
NOTE
The default redistribution action is permit, even after you congure and apply redistribution lters to the virtual routing interface.
If you want to tightly control redistribution, apply a lter to deny all routes as the last lter (the lter with the highest ID), and then
apply lters to allow specic routes.
A route map is a named set of match conditions and parameter settings that the Brocade device can use to modify route attributes and
to control redistribution of the routes into other protocols. A route map consists of a sequence of up to 50 instances. The Brocade device
evaluates a route according to a route map’s instances in ascending numerical order. The route is rst compared against instance 1, then
against instance 2, and so on. If a match is found, the Brocade device stops evaluating the route against the route map instances.
Route maps can contain match statements and set statements. Each route map contains a permit or deny action for routes that match
the match statements:
• If the route map contains a permit action, a route that matches a match statement is permitted; otherwise, the route is denied.
• If the route map contains a deny action, a route that matches a match statement is denied.
• If a route does not match any match statements in the route map, the route is denied. This is the default action. To change the
default action, congure the last match statement in the last instance of the route map to "permit any any".
• If there is no match statement, the route is considered to be a match.
• For route maps that contain address lters, AS-path lters, or community lters, if the action specied by a lter conicts with
the action specied by the route map, the route map’s action takes precedence over the individual lter’s action.
If the route map contains set statements, routes that are permitted by the route map’s match statements are modied according to the
set statements.
In RIP, the match statements are based on prex lists and access control lists. Set statements are based on tag values and metric values.
To congure redistribution lters, enter the following command.
device(config-rip-router)# redistribute connected route-map routemap1
Syntax: [no] redistribute {connected | bgp | ospf | static [metric value | route-map name]}
The connected keyword applies redistribution to connected types.
The bgp keyword applies redistribution to BGP4 routes.
The ospf keyword applies redistribution to OSPF routes.
