Usage
Information
BGP to IS-IS redistribution supports “match” options using route maps. The metric value, level, and 
metric-type of redistributed routes can be set by the redistribution command. More advanced “set” 
options can be performed using route maps. 
redistribute ospf 
e
Redistribute routing information from an OSPF process.
Syntax
redistribute ospf process-id [level-1| level-1-2 | level-2] [match {internal | external}] 
[metric metric-value] [metric-type {external | internal}] [route-map map-name]
To return to the default values, enter the no redistribute ospf process-id [level-1| level-1-2 | 
level-2] [match {internal | external}] [metric metric-value][metric-type {external | 
internal}] [route-map map-name] command.
Parameters
 
Defaults
As above
Command Modes
ROUTER ISIS (for IPv4)
CONFIGURATION-ROUTER-ISIS-ADDRESS-FAMILY-IPV6 (for IPv6)
process-id
Enter a number that corresponds to the OSPF process ID to be redistributed.
Range: 1 to 65355
metric metric-value
(OPTIONAL) The value used for the redistributed route. You should use a 
metric value that is consistent with the destination protocol. 
Range: 0 to 16777215
Default: 0. 
metric-type {external | 
internal} 
(OPTIONAL) The external link type associated with the default route 
advertised into a routing domain. The two options are: 
• external
• internal
level-1
(OPTIONAL) Routes are independently redistributed into IS-IS as Level 1 
routes. 
level-1-2
(OPTIONAL) Routes are independently redistributed into IS-IS as Level-1-2 
routes. 
level-2
(OPTIONAL) Routes are independently redistributed into IS-IS as Level 2 
routes.
This is the default. 
match {external | 
internal} 
(OPTIONAL) The command used for OSPF to route and redistribute into 
other routing domains. The values are
• internal
• external
route-map map-name map-name is an identifier for a configured route map.
The route map should filter imported routes from the source routing protocol 
to the current routing protocol. 
If you do not specify a 
map-name, all routes are redistributed. If you 
specify a keyword, but fail to list route map tags, no routes will be imported.
