Route Maps
Use to enable BGP route flap dampening only on routes that pass the match
clauses of, and are redistributed by, a particular route map.
BGP creates a dampening parameter block for each unique set of dampening
parameters such as suppress threshold, reuse threshold, and so on used by
BGP. For example, if you have a route map that sets the dampening parameters
to one set of values for some routes and to another set of values for the remaining
routes, BGP uses and stores two dampening parameter blocks, one for each set.
Example
host1(config-route-map)#set dampening 5 1000 1500 45 15
Use the no version to delete the set clause from a route map.
See set dampening.
Use to set the administrative distance on routes being installed into the routing
table that match the route map.
Distance establishes preference between routes to the same prefix to identify
the best route to that prefix. Setting distance in any other circumstance has no
effect.
Example
host1(config-route-map)#set distance 5
Use the no version to delete the set clause from a route map.
See set distance.
Use to set the extended community attributes in a route map for BGP updates.
You can specify a site-of-origin (soo) extended community and a route target
(rt) extended community at the same time in a set clause without overwriting
the other.
Example
host1(config-route-map)#set extcommunity rt 10.10.10.2:325
Use the no version to delete the set clause from a route map.
See set extcommunity.
Use to set the next hop attribute of a route that matches a route map.
You can specify an IP address or an interface as the next hop.
Use the peer-address keyword to have the following effect:
On outbound route maps, disables the next-hop calculation by setting the
next hop to the IP address of the BGP device
