The as-path prepend <num,num,...> parameter adds the specified AS numbers to the front of the AS-path list for
the route.
The automatic-tag parameter calculates and sets an automatic tag value for the route.
NOTE: This parameter applies only to routes redistributed into OSPF.
The comm-list parameter deletes a community from a BGP4 route’s community attributes field.
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’s
penalty becomes half its value. The <reuse> parameter specifies how low a route’s penalty must become before
the route becomes eligible for use again after being suppressed. The <suppress> parameter specifies how high a
route’s penalty can become before the Layer 3 Switch 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. For information and examples, see “Configuring Route Flap Dampening” on page 21-58.
The [default] interface null0 parameter redirects the traffic to the specified interface. You can send the traffic to
the null0 interface, which is the same as dropping the traffic. You can specify more than one interface, in which
case the Layer 3 Switch uses the first available port. If the first port is unavailable, the Layer 3 Switch sends the
traffic to the next port in the list. If you specify default, the route map redirects the traffic to the specified interface
only if the Layer 3 Switch does not already have explicit routing information for the traffic. This option is used in
Policy-Based Routing (PBR).
The ip [default] next hop <ip-addr> parameter sets the next-hop IP address for traffic that matches a match
statement in the route map. If you specify default, the route map sets the next-hop gateway only if the Layer 3
Switch does not already have explicit routing information for the traffic. This option is used in Policy-Based
Routing (PBR).
The ip next-hop peer-address parameter sets the BGP4 next hop for a route to the specified neighbor address.
The local-preference <num> parameter sets the local preference for the route. You can set the preference to a
value from 0 – 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 – 4294967295.
set metric <num> – Sets the route’s metric to the number you specify.
set metric +<num> – Increases route’s metric by the number you specify.
set metric -<num> – Decreases route’s 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 | type-2 parameter changes the metric type of a route redistributed into OSPF.
