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.
