Enabling route redistribution
This step enables ASBR operation on a routing switch, and must be executed on each routing switch connected to external routes you want to redistribute in your OSPF domain.
The basic form of the
redistribute
command redistributes all routes of the selected type. For finer control over route selection and modification of route properties, you can specify the
route-map
parameter and the name of a route map. (For general information on route policy and route maps, see
Route Policy. For examples of using route maps in route redistribution, see
Using route policy in route redistribution.)
Do not enable redistribution until you have configured the redistribution "restrict" filters. Otherwise, the network might become overloaded with routes that you did not intend to redistribute.
Syntax:
[no] router ospf redistribute [connected | static | rip] route-map name
Executed on an ASBR to globally enable redistribution of the specified route type to the OSPF domain through the area in which the ASBR resides.
static
Redistribute from manually configured routes.
connected
Redistribute from locally connected networks.
rip
Redistribute from RIP routes.
route-map name
Optionally specify the name of a route-map to apply during redistribution.
The
no
form of the command disables redistribution for the specified route type.
Example
To enable redistribution of all supported external route types through a given ASBR, execute the following commands.
switch(config)# router ospf redistribution connected switch(config)# router ospf redistribution static switch(config)# router ospf redistribution rip
