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.
AS number
Enter a number that corresponds to the Autonomous System number.
Range: 1 to 65355
level-1
(OPTIONAL) Routes are independently redistributed into IS-IS Level 1
routes only
level-1-2
(OPTIONAL) Routes are independently redistributed into IS-IS Level 1 and
Level 2 routes.
level-2
(OPTIONAL) Routes are independently redistributed into IS-IS as Level 2
routes only.
This is the default.
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

metric-type {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.
