Filtering
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 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, refer to
“Route flap dampening configuration” on page 354.
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 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 route metric 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 | type-2 parameter changes the metric type of a route redistributed into
OSPF.
The metric-type internal parameter sets the route's 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 router.
The nlri multicast | unicast | multicast unicast parameter redistributes routes into the multicast
Routing Information Base (RIB) instead of the unicast RIB.
NOTE
Setting the NLRI type to multicast applies only when you are using the route map to redistribute
directly-connected routes. Otherwise, the set option is ignored.
The origin igp | incomplete parameter sets the route origin to IGP or INCOMPLETE.
The tag tag-value parameter sets the route tag. You can specify a tag value from 0 through
4294967295.
