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 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. For information
and examples, refer to
“Configuring route flap dampening”
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 – 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).
