Usage
Information
With FTOS version 8.3.1.0 and later, the redistribute command can be used to advertise the IGP cost as
the MED
on redistributed routes
. When the route-map is set with metric-type internal and applied
outbound to an EBGP peer/peer-group, the advertised routes corresponding to those peer/peer-group
will have IGP cost set as MED.
IS-IS to BGP redistribution supports matching of
level-1
or
level-2
routes
or all routes (default). More
advanced match options can be performed using route maps. The metric value of redistributed routes
can be set by the redistribution command.
Command
History
redistribute ospf
c e s
Redistribute OSPF routes into BGP.
Syntax redistribute ospf process-id
[[
match external
{
1
|
2
}] [
match internal
]] [
route-map
map-name
]
To stop redistribution of OSPF routes, use the
no redistribute ospf process-id
command.
level-1-2
(OPTIONAL) Enter the keyword
level-1-2
to independently redistributed
into Level 1 and Level 2 routes. This is the default.
level-2
(OPTIONAL) Enter the keyword
level-2
to independently redistributed into
Level 2 routes only
metric metric-value
(OPTIONAL) Enter the keyword
metric
followed by the metric value used
for the redistributed route. Use a metric value that is consistent with the
destination protocol.
Range: 0 to 16777215
Default: 0
route-map map-name
Enter the keyword
route-map
followed by the map name that 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.

route-map is set as internal.
