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.
WORD
ISO routing area tag
level-1 (OPTIONAL) Enter the keyword level-1 to independently redistributed into
Level 1 routes only.
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.
