The comm-list parameter deletes a community from the community attributes field for a BGP4 route.

The community parameter sets the community attribute for the route to the number or well-known type
you specify.

The dampening [half-life reuse suppress max-suppress-time ] parameter sets route dampening
parameters for the route. The half-life parameter specifies the number of minutes after which the route
penalty becomes half its value. The reuse parameter specifies how low a route penalty must become
before the route becomes eligible for use again after being suppressed. The suppress parameter
specifies how high a route penalty can become before the device suppresses the route. The max-
suppress-time
parameter specifies the maximum number of minutes that a route can be suppressed
regardless of how unstable it is.

The ip next hop ip-addr parameter sets the next-hop IP address for route that matches a match
statement in the route map.

The ip next-hop peer-address parameter sets the BGP4 next hop for a route to the neighbor address.

The local-preference num parameter sets the local preference for the route. You can set the
preference to a value from 0 through 4294967295.

The metric [+ |-]num | none parameter sets the MED (metric) value for the route. The default MED
value is 0. You can set the preference to a value from 0 through 4294967295.

set metric num - Sets the metric for the route to the number you specify.
set metric + num - Increases route metric by the number you specify.
set metric - num - Decreases route metric by the number you specify.
set metric none - Removes the metric from the route (removes the MED attribute from the BGP4

route).

The metric-type type-1 and type-2 parameters change the metric type of a route redistributed into
OSPF.

The metric-type internal parameter sets the route MED to the same value as the IGP metric of the
BGP4 next-hop route. The parameter does this when advertising a BGP4 route to an EBGP neighbor.

The next-hop ip-addr parameter sets the IP address of the route next-hop device.

The origin igp incomplete parameter sets the route origin to IGP or INCOMPLETE.

The tagtag-value parameter sets the route tag. You can specify a tag value from 0 through
4294967295.

NOTE
This parameter applies only to routes redistributed into OSPF.

NOTE
You also can set the tag value using a table map. The table map changes the value only when the
device places the route in the IP route table instead of changing the value in the BGP4 route table.

The weight num parameter sets the weight for the route. The range for the weight value is 0 through
4294967295.

Setting a BGP4 route MED to equal the next-hop route IGP metric

To set a route's MED to the same value as the IGP metric of the BGP4 next-hop route, when
advertising the route to a neighbor, enter commands such as the following.

device(config)# access-list 1 permit 192.168.9.0 0.0.0.255
